What a wonderful creation you've made Lenny! I really love the head, but really, the whole dragon just oozes character. This is a real step up from your last big dragon, just color me impressed.
I only have two points of criticism.
First, I'm not liking the joints in the neck and tail. They're too spindly and make him look too segmented. Admitedly, however, I have no clue how to rectify it without totally redesigning him, and it might just take away from his charm.
Second, he doesn't look like a Horatio. He looks like a George, or a Mortimer (Morty). Maybe a Floyd. But that's just the way I feel about it
Great job as always.
