I love that little budda statue. He makes my day pretty much everytime I see him! :)
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.
Hahaha, the 80s was the best era for sure.
Continue to think about the basic structure of things - your skulls/faces are looking a bit unsure of where things are supposed to go. (I'm noticing this consistently in where you're placing your mouths below their noses when you draw faces straight-on -- you're not putting them on the same curve of the face, but slightly off to one side or the other. To help you line it up, remember the philtrum extends down from the inner break in the nose, and that will always help you place your mouth below your nose. You seem to place the philtrum always just slightly to the side, but I think it might be because you're unsure where the base of the nose is connecting to the face to help you get the philtrum-guide down. Might be good to do some studies of noses from different angles to help you get a better feel of where it's supposed to go?)
Vine charcoal looks like it's a nice medium. Is it tinted that slightly brown/reddish color or is just the color those drawings are scanning in at? (I like the color - it looks kind of cool.)
I like the idea for the bard. (I LOVE the 80s. So many songs from that era on my 'guilty pleasure' playlist. XD) I be curious to see what you do with it. (I like the quick study for the boom box. That came out cool.) His head is slightly lopsided to our left at the moment - don't forget to flip the image to help you correct things like this. (Very helpful trick!)
Keep it up!
