Your artwork is looking great! I'm noticing major improvements from the earlier stuff. I think my biggest crit would have to be the amount of lines you use. It gives the pencil drawing a cool, detailed look, but if those lines were to be inked, much of that detail may become a bit of a mess, and a lot of the depth that's there with the encil would be lost with the inks.
It looks like you cut down a lot on your amount of lines with the latest update, and I have to say the image reads much better. It may not have that cool McFarlene-esque detail in it like your earlier stuff, but it a hell of a lot more coherent, and when you're drawing sequencial art coherency is the MOST important thing.
Keep up the good work, I can't wait to see more!
