Those lines are incredibly messy, they should only be 1px wide at every point. I suggest going back and cleaning them up. There's also very little contrast on the creature, which makes it appear flat. I do like your concept though, and I really hope you'll revisit this piece in time!
yeah I really half assed this one, I just sort of scratched out the basic shape and painted it straight off the bat without any attempt at sculpting, I don't think I'll ever revisit this as I'm gonna be horrifically busy for a while learning 3d modeling, animation and texturing and I already have enough neglected pixel art pieces that could use a little love. Thankyou for the feedback :)
