One thing i wanna say if i may, irrelevant as it is to the current sprite, your process could use some fixing. When you start with a skeleton almost for fun i notice that you deal with the issues related to proportion and whatnot later rather than during the skeleton phase as you should. I can undrestand its a bit tough to imagine the body without and features and try to find mistakes but otherwise the more detail you add the harder it will become to fix anatomical issues as well as proportional issues.
Onto the actual drawing. The scarf looks pretty good but its not cohesive with his clothes. The clothes are shaded with 2 colours whereas the scarf is shaded with 3 or 4 colours (although that detail isnt really important i thought it was necessary)
Ribcage is still pretty small and you have a bit of a tangent between the belly button line and the lines in the bands around his stomac (just look up what a tangent is ((its when things line up weird)))
I dotn understant why everythign else is painted kinda whereas the face is drawn with black outlines, it looks kinda silly.
Scarfs better but meh. theres something off about it, look to a real scarf for reference.
