It seems that I didn't make it to the challenge's deadline but I want to upload my progress so far. I'll definetively finish this piece, I'm learning so much.
I've been strugling with rendering materials and using the correct brushes, it seems easiest to me using oils and traditional media. I would like to hear comments, tips, and critiques. Please feel free to write. The finished piece will be posted in a forum of Cubebrush and in my social media.
