Good start..... Few suggestions....
Just watch your proportions and shape.... the breasts need some work from the collar bone down... Also the back side (bum) where the fleshy part is connecting to the lower back needs to come down a bit.. just grab the verts and move them down.
The arms and shoulders are looking good so far.
