tutorials won't teach you anything, there is no right solution how to draw a dragon in a storm but there are several possibilities. Thought and theory won't help you here,
But then the shading and highlighting. I am pretty much entirely self-taught and found really helpful tutorials all over the net, but working with strong contrasts and daring light sources are a pain. I really need some help with this, guidelines as to how I can make a subject look like it's actually in there, blending in with the background but still jumping out. Whatever I try, I just really can't seem to pull it off.
