Arm-y Of Darkness

here's a collection of pencil sketches, drawn on various bits of note paper. there's some shocking anatomy on there, but some of it works too! when i learn anatomy, firstly I tend to focus purely on the muscle arrangement (like an ecorché study). When i get that nailed, i go back and work out how fat changes the definition and shading (often completely hiding those muscles i spent so long learning where to put!)
