What an amazing piece of art. You should join the Level Up! community on Facebook. www.facebook.com/groups/levelu…; They're amazing, there's tons of industry artists on there, they give critiques, post art, and the community has a website as well, with livestream videos they do every so often with guest appearances. (www.fusroda.com) and they have dedicated Google Hangouts! so you can paint with others, via screen sharing; talk about art, etc. I think someone of your skill level would really benefit from it! (and the community would benefit from having you, too!)
Cheers, and I hope to see more of your amazing art in the future!
