I have a little suggestion that probably would help many others. I think many people have trouble with the outsole. So from those sketches you made, possibly make some outsole sketches to go along with it as proportions on the outsole are somewhat hard to get. Maybe also throw in some heel view sketches. I think some people like me, can get a decent proportioned lateral view going, but when it comes to translating the outsole from that view, it seems a little off.
