I have being reading all the coments daily but I was busy with some stuff at work to post a response inmediatly. Thanks to everyone! I have enjoyed your advice.

What was the tripod on? You might have some vibration or wind blur that affected the sharpness. And since everything is at infinity, you could have used 8 sec @ f/8:
DOFMaster Depth of Field Calculator
with apps for iphone, ipod, palm, android, windoze...
Thanks for the info, I used 30s for the light effect, I will read and study DOF, as I understand it but dont really apply it in my photos, I think that might be the issue, and thanks for the link, I downloaded the app for my phone!

I believe the 1st 2 are losing sharpness due to diffraction at those small f-stops. You don't need to go smaller than f-11 @ those distances & focal length combos to get sufficient DOF!
ALSO- in #2 a ND grad would help better balance the foregrd to sky/bkgrd exposure here.
Thanks for the advice I will check the f situation with diffraction.

If using a tripod, you want to turn IS off, otherwise it will cause issues quite similar to the lack of sharpness in image #1. EXIF says manual focus for the first pic - did you possibly just miss focus? Or as Photosguy asked - possible vibration through the tripod? Nice composition - would have been a keeper if sharper.
Thanks, yes IS was on, for the manual focus I use liveview with 10x magnification on a building in the middle.
It might be vibration but I didnt use a tripod as I dont have one, only placed the cam on a flat piece of wood I found and used my wallet to regulate angle, so it was quite sturdy I think, maybe wind or maybe all the earthquakes we are having! a small one ocurring when my pic was taken haha!

Even with a sharp lens and perfect technique, objects in the distance can be soft due to atmospheric distortion.
I was thinking something like this also, maybe something but I remember that day being clear.

Now the candle.........Few things in your photo life will be more difficult than this shot that you want. The reason is something called dynamic range. Your camera can only capture about 10-12 stops of light. So to get the flame with the texture you want, you probably need to be at about 1/30 to 1/60 second. BUT if you do that, then the candle and everything else around it will be too dark because the light falls off really fast (according to the inverse square law). If you expose for everything else, then your flame washes out. So you are forced to do some tricky things.
One thing you can do is provide ambient or supplemental flash light to bring the base exposure up. But if you do that, you end up losing some of the "glow" from the flame. Your next option is to creatively control your flash or some kind of constant light source to provide a glowing light effect on top of the flame itself so that it mimics the glow of the flame while providing extra light to the subject. The 3rd way to do this is with multiple exposures - one for the flame and another for the candle and background with the glow. In this case you could layer one over the other in photoshop and then use a mask to paint out the overexposed flame and reveal the properly exposed flame. This would probably be the easiest method, but sometimes, especially if you had a model holding a candelabra, you just can't expect to get multiple shots that are exact enough to do this. So you have to resort to creative lighting.
For a few months you're doing well. Keep it up!
Thanks for this!, I might try multiple exposures.
Thanks a lot for your advice, I will study DOF as I think this is something Im not considering at my pics and might improve a lot the quality.
As for my Lens I have been experiencing some issues with the 18-55, slow and inaccurate focus, harsh barrel movement (I think there's some sand in there) and I found dust in the inside elements, I have being reading how to clean it so as for now im looking foward to get my hands on some compressed air.
As this happend, this week just took some experimental photos. Like this one.
To correct this lens problem...
I got a pair of new ones from amazon today, a 'Tokina 11-16 f/2.8' and a 'Canon 50mm f/1.8', and a few other stuff to play with*, Expecting this to arrive in a few weeks! very excited.
*Hoya ND32 Filter
*Hoya CPL Filter
*Holga Lens? just for curiosity.
*M42 adapter to use with a very old Helios 44mm f2 lens I have.
Have a good weekend everyone! There's a big regatta this weekend here so I will try to get some nice pics with my newly acquired DOF knowledge
