My honest opinion. At first I thought we'll be definitely playing as a goat, until I get to the game where he is a Dragon, although despite that, the current design never made me feel like he is a Dragon. Though still cute, but indeed I agree that it was a little off.
Design one seems to not change much and stayed cute.
Two still cute, but with more detail.
Third however is completely somehow different on my perspective. Like his much older than what it seems on the game. And I like that, a bit maturity to fit his environment. Because the current one seems like, a face of a submissive bottom, apologies if that seems like I'm stereotyping. The characteristics of the norm is engraved to me
