I browsed through some of your pencil drawings posted here and wanted to tell you something I noticed in all of them. Your line art is very rigid. While I really find this helpful for scans (I often had problems with nearly invisible lines when I drew earlier), I'd love to see your drawings loosen up and relax. You are working on proportions, but also on getting the lines where you want them, and I think it could help you to soften the lines. You are drawing like a weightlifter, which I mean to be no offense. I absolutely see something in your drawings (would not have replied otherwise). Keep going, you are on a way!
