Personally your line work caught my attention, its not focused and uses a lot of the same cloned thickness and shapes leaving it dry like arizona with no variation. I feel if you aimed at making things more line diverse, flawed and alien then basing it off simple design you may have something grand here. Id like to see textures, different fur detailing and styles mature on things like this over time.
You have something, but it's lacking even with the energy it has. Id bet a lot of ivory or seaglass once you start focusing on anatomy, toned detailing and such you'd be a riot good digital artist.
PS. I swear I saw that version of Nick somewhere before, it hits a lot of bells and neurons firing. Its strange, abstract but kind of good if not for its scary proportions.
