After beating my head in for a good few hours I tried coming up with some reliable method of drawing Dylan's head. So far this seems like a good start and so far has proven easier than past methods. Time will tell how useful it will be or how long it will last.
I like the ears--they kind of remind me of Stitch's from Lilo and Stitch and Rabbit's from Winnie the Pooh. They're rather expressive like theirs are, and I guess combined with the shape you get the resemblance (at least in my eyes anyways).
yeah, I've felt recently that his ears needs a more defined shape to them, and armadillo ears generally curl inward like that. Dylan's ears are probably quite a bit bigger than normal Armadillo ears but I think he looks better this way.
I personally like them how they are too. It shows you're able to take a bit more of creative licensing with the actual species your character is based on to better formulate the actual design to your liking.
