The university is having an "Earth Day" themed art contest coming up with $200 up for first place. I've already got two old photos I'm going to enter, but I can't decide which of these I like best. So, pick which one you like, 1-4 as displayed. Explain your choice if you like. C&C welcome as well, I have all of these in RAW so I have a lot of room to work with them.

Also, they have to be printed and framed, so if you have any thoughts on that, let me know. I'm thinking metallic paper? Thanks for your help, I'll let yall know if I win anything!

Just my opinion, #4 has the lightest back round. The other back rounds just seem to take away from the subject.

4 for me, 1 is OK. 2 and 3 aren't very special.

#4 all of the way. Me being me I want to crop a little on the right. :D

Thank you, everyone, for the votes and comments! By all means, I'm not emotionally attached to these, so if you find that don't like any of them, please say so! I'd rather hear it here and now than from a judge.

So far it's 90% for # 4, 10% for # 1... keep 'em coming!

4, got my vote.

Definitely #4. As mentioned, the backgrounds on the other ones are too dark.

I like number 1 and number 2
The flowers really pop against the naturally dark background

I'm thinking this would be better on Photo Critique?
