Thanks for the reply, but i can alway use the screenshot for perspective and draw above it (dont know the term for using something like a photo and outline it to your own drawing)?
Probably. I'm no expert, so this is just a guess: you need to be careful when you are doing it for commercial purposes. If there were no money involved, then I'd say go for it. Because that is just artistic expression or something like that. But, what you are doing is taking somebody's work, slightly alter it, and then profit from it.
