Shit man. Those pencil drawings at the top of this page are nuts. Absolutely lovely rendering and textures on those.
The gray scale digital painting is a bit iffy. Your values are kinda all over the place, no one character is given a ton of focus, it's all kinda spread over the place and the composition is a little awkward because of it. Try using some bigger digital brushes when you're starting out, might help to resolve that a bit.
More updates please. :3
