Mini compositions/ Sketches

I tried to do some black watercolour thumbnails for fun to see if any interesting compositions came out of it. As it turns out, coming up with concepts without direction is quite the challenge. I did like the dragon composition so I was going to take that further but haven't gotten very far as you can see.. I also developed some cyborgish extraterrestrial but I later randomly found something similar on the internet so gave that one up as it obviously wasn't creative enough.

I really want to do some zombies for my portfolio and I've been inspired to do some walk cycles.. so I need to come up with some critters/ characters to model.
