I like the subject in #1 - very cute. And, #2 is okay. Otherwise, I don't like the vignettes and the compositions are weak. I'd like to see more of your work, but with less processing and better poses and composition.
The first photo is the set is very odd. Was he really in the grass? He looks super imposed in the setting. His left shoulder also appears to be missing?
The fourth photo is my favorite from this set, but I really do not care for he vignette.
The vignette in all of the photos is too strong, IMO
