The Last KP drawing It's okay to go on hiatus. We all hit a creative block. I had mine last year and I just felt "all drawn out" and wasn't really getting much in the way of feedback. But eventually I hit my stride again and new ideas popped into my head!
So this is your "last" for the time being I can at least say you were improving,that the characters were beginning to stand out more and seem more expressive. The world they inhabited reminded me of both the Stange Island of Dr. Moreau and Secret Of NIMH. The first dealt with splicing human and animal DNA together whereas the later was inspired by the Utopia Rat Experiment but with the added wrinkle of certain mice and rats becoming super intelligent.
Visually your stuff always reminded me a bit of Invader ZIM, Ren and Skimpy,as well as even an episode/movie of Batman Beyond in which the Joker and Harley turned Tim Drake into a "Joker Junior" of sorts. Honestly it's not quite "my preferred niche" but I recognize it still has a lot of potential and there is an originality and flare to your work I don't often see.
Anyway, take a break man but don't give up completely. Not unless you find another art,craft, or career path in your life you are just as passionate if not more so about!
