I like them, but for cc- #1 I can't help but immediately notice the missing fingertips. You *might* be able to clone one back in, otherwise keep it in mind next time.
#2 his near eye doesn't appear to be in focus. Even when using a shallow depth of field you need both eyes in focus.
#3 I would lower the brightness-
#4 tight crop on the arm- cute shot but it needs some breathing room.
