I think it rocks.
I feel the lower jaw is too weak, or small. Everything feels purrfect except the neck, and how the head connects.
I think the head is just a little too small, yeah, it feels like it is 5% too small, and the bicepts and shoulders are too thick.
just an observation
probably the tail would be lower, at the tailbone between the cheeks, it looks too high,
Man, this inspires me, thanks!
You are more than a noob!
