The composition here is very nice - I like the squarish crop, the bud in front of the OOF blooming roses, and the smaller buds below. Not sure if you saw the spider webs and mites before you shot, but next time you can try hosing off the plant a little before you take the picture (I know, because I have the same problems with my roses.)
I've seen a lot of plants and trees... Yes, they meet the challenge, but where is the creativity... It's the image that stands out from the rest that wins me over.
