Well this is the first time I had ever won any photo contest, and it is also the first time I have had to judge any photo contest, so it's going to be a bit tricky for me.
Please don't take any of this seriously, I am not a technical guy as far as judging photos go, so if I say something that makes no sense to the real photogs out there, sorry, I am just looking at them on a punter level.
Ok:
Hawkeye: didn't you get the memo? , white is the new black! 
I like how you did the color change, it's given me hints on how it's done, which was another thing i wanted to find out how it's done, so thanks. BUT, it's not a fiesta, this car actually packs some punch (250KW 4 litre turbo 6) but if I lined up in a lemon colored car with silver wheels, it would HAVE to be quick! Not sure about the fragmenting in the clouds (is that the right word?)
Lore: such a nice mod in my eyes, and brought out a lot of detail in the shadows which is nice. even a number plate (sorry 'bout cutting mine out, but I gotta have some anononimity on the web!) I would have given it a little more saturation, and the rear of the car to me is a little washed out or something, but apart from that, it's a really nice image.
Ocron: nice, I like how you got the effect with the wheels. They are just factory painted, but they almost look like chrome silver in your pic. One of the nicest sunset mods so far and matches the colors we get most late afternoons at this spot. Made the tint look nice and black
tkbslc: not sure how to take this one, the way you gave the white a metallic look is really nice, but the whole pic is just too dark for my liking. The red in the sunset is very much like we get in summer just as it's gone over the horizon and there is some cloud to bounce it back, if only the rest of the image had more exposure to suit that sky.....I have a photo of the same place and the whole image is blood red, exactly like the water in your pic.
masterwillems: mmm, I spend a lot of effort trying to get the blur OUT of my pics, and you put 'em right back in again! 
I think I know what you were trying to do, but maybe it was the wrong shot for that? Maybe more color would have helped? I'm really sorry and i don't want to sound mean or anything, but it just doesn't do anything for me.
SilverHCIC: Very nice, no crazy mods, just a nice mood to the picture, would have been perfect if you brought out some of the details in the shadows around the wheel wells and tyres like lore did. The frame really helps clean it up, but it wouldn't have been my first choice in style. I don't know what frame I would have picked of course!
kendoway: "dude, where's my car!"
Apart from the funky shoreline in a spot, it's actually a prety good translation of what it looks like! The moon is cool, even though we aren't going to see any full moons within 15 degress of where the sun is setting at the same time this shot was taken! oh, and about my car..........
MJA: wow, nice effect, and again that nice metallic look to the wheels like ocron did. I like how it gives the effect of a light from below, very nice. it does look though like the car has lost some of it's shine in the rear quarter area. almost has a matte look to it which takes away from it slightly.
Ok, there's my take on the images. They are only my humble newby views so please take any critisism with a grain of salt.
One thing I noticed is apart from kendoway, who removed my WHOLE car!, I thought someone would have cloned out those ugly looking reverse sensors in the rear bumper.... but anyway.
It's really between Lore, Silver, and MJA. If only I could blend all the individual bits I like in each it would make this very easy....
I have learned a lot just from this thread, and the biggest thing I have learnt is I hate judging others work....!
OK, the winner is...............oh damn it, I still can't pick one so I asked my wife and two boys to pick one from the three I picked......and you guessed it, they all picked one each!! That puts it back to me. 
I am going to pick MJA as the "winner".
I just like the colors, the gradients, it's got a pastel look to it, oh i don't know, I just like it 
Far out, I didn't think it would be this hard to pic a pic!
Ok, MJA, over to you, it's been a lot of fun watching my pics get modified and learning how it's done, but you can have it !!!
Cheers
