Yeah, I can relate to that. Sometimes it's hard to find inspiration, and even harder to find the motivation. It's a natural phase of the creative process though, and it always passes. And in the meantime, I'm happy to collaborate until you find that sparkle. :)
Like I said before, I can do the framework/skeleton of the dragon and you can do the body. Then we can split detailing and each add our own little flair to it. Then maybe we could split the coloring too. Like I'll color the background and you color the dragon? If you want to do color, that is! Or I could even do inking and you could color it. There's a lot of ways we can split up the responsibilities, haha.
I'd like to stay with pencil drawing, since you're really good at it. Are you going to be able to print out and draw on the picture I'll send you? Or is there another way you'd like to work on the picture? Just tell me what you need me to do to start the collaborative piece. :)
