Love love love love loooveee!!! Your anatomy and attentiveness with the skeletal structure underneath is beautiful!!!! And while your pose and anatomy is jaw-dropping, you can work on muscle shape and definition! Utterly stunning, keep goingg!!
Oh and the 5th one, the chest is kinda pressed together and unless shes wearing something that constricts them like that, there should be a gap between them! Again, beautiful and happy drawing!!
