I have a couple of those laughing Buddha's aswell.
I think you've done significant progress from the last time I peeked in here.
Something to consider though. On the Charmander piece, I think you have gone into way too much detail way too early. Figuring out composition, perspective, general construction, main and subsidiary lightsources, fore- mid- and background etc. is of key importance.
Not only does it hinder you from seeing the piece as a whole, when you scrub too much detail into parts and later have to do major changes, your time has gone to waste. I think of drawing more as sculpting the figures and surroundings out of light, first with just building the shapes and forms and moving from there on.
I hope this helps, keep it up.
