Have seen your work here before - it was good then and it is good now. I see an improvement, also. The colors are excellent in my opinion (not too muted but not at all garish).
My, oh my you are quite the Artist.
Great work I love the First one with the Skulls and I think it is the best one, I can only hope to become a great Artist like you.
Your technique is pretty outstanding You have a really good eye for shade/shadow/color, as well as finer complexities and detail. Your composition is excellent.
I'd be curious to see how you would draw something a bit less organic, however, like a building or some inanimate object.
I have drawings of inanimate objects/less organic ones - however prefer and have more interest in working with the more organic forms. who knows, may gain more interest in buildings and such - always up for taking things to a new level
