VERY underexposed, need more lights, use a slave and softbox's, get rid of the flash.
Is this a chicken? lol If so...its hard to tell, you need to really work on posing. Guessing a 4-6mth old bub? In our studio 4-6 mths we use props such as small chairs, bean bags and bub on top looking over on their tum, back shots laying in bean bag again, also using props qwhere bubs can sit inside and be supported. Babies need a lot of support to make a shot look good. ALSO tripod is a must for a lot of studio shots.
Bubs has dead eyes, which means there are no highlights, you need to be slightly higher than bubs then shoot down a tiny bit, get bub to look UP (Distract with bells etc) so then the lights highlight his eyes.
Hopefully this helps, its just general knowledge from working in a studio environment epesh with bubs and kids
