Sorry to be so cut and dry. The Challenge purpose is to try and 'fit' all of those random objects into a single picture. Maybe the board didn't explain that well in the details...I can't speak for them. As far as the actual photograph goes- you placed it because it fit the 'vase' requirment- but the vase itself is underexposed and hidden. The flowers are nothing special to me- it looks like flowers that I've seen before and it's from an angle that I've seen them at.
I hope this helps a bit.
I like the colors a great deal - the yellows and reds and greens are quite well done. Looking at the challenge description - My one question is - where is the body part?
