some pics C&C welcome

I like this one the most. I would crop out the stem to the bottom left and the dark spot to the bottom right.

Even though there is seperation of the flowers to front from those in the rare the yellow behind somehow detracts from the foreground flowers.

same as above except the white background is guilty

I like these. Try a sepia effect to see how it might look.

Colour instead of black and white my raise my interst on this shot.

Overall to me they are a nice set. The thing about flowers is that they arent going anywhere so take your time and work on your compositions.
