Heres a couple

Please tell me what you think.

top one looks over saturated

firework shot remove the bright dot near the bottom my eye went right too it....

In both photos you have interesting skies (fireworks are essentially a decorated sky) with nice colors and textures. That sunset is the stuff that photography dreams are made of and must have been fantastic to witness. What would really push either one of these into an exciting photographic presentation would be better composition that provides a thoughtful foreground/base for the sky.

In the sunset shot, we see a fringe of silhouettes at the bottom that looks quite random, as if you included those elements only because they were in the way of the sky. Remember that you as the photographer are responsible for everything in the frame: you need to 'organize' the elements through positioning yourself and framing selectively. Finding a compelling foreground or silhouette for a sunset can be very difficult in busy urban environments, but it can be done. Your best bet is to find a good 'subject' to put in front of the sky well before the sunset begins; an interesting building, tree, bridge, lamp post, statue, etc.--anything that can anchor the frame, provide scale, and give the viewer a sense of place. If you get caught without having planned ahead, you can always get creative with your own silhouette in a pinch: put that self-timer to work for you!

In the fireworks photo, you simply have no foreground or base. Fireworks are pretty, but they are a lot more impressive in photos when you have a sense of scale and place to go along with them. Some examples.

Hope that helps.

Pretty dramatic sky in the sunset photo but it's ruined with everything at the bottom of the frame. Sunsets are beautiful, but unless you've got strong composition and framing their probably better served to just watch and not photograph. I know how tempting they are to shoot, but you have to be able to recongnize when you can get a good photo and when you can't. What you've presented is an example of when you can't. If you're set on photographing the sunset then take the time to find a suitable spot and pay attention to your composition and everything else in the frame. Sometimes cultural objects like buildings and roof tops can make a great foreground for a sunset but you have to find the right spot.

On the good side, I really like the colors you captured in the sky.

The fireworks shot....well...it's a black square with a burts of light. There's nothing grounding the photo. The firework's upward trail seems to come from nowhere (though we know it came from the ground) and makes the photo look "off".

I definitely see what you guys are saying. I didn't do any post production. This was straight out of the camera. Both were shot with my 5d mk 3 and 70-200 L II. Thanks for the advice!
