Yezukh'ay is of a different dragon-ish species (Suyen) than my favorite (Gwil), and I've been working on differentiating them. Suyen are small, have a paddle-shaped tail, different skin and eye tone, and drooped ears. For this iteration, I'm also trying out having them... not be mammals... and having a longer snout than Gwils. Basically making them more like Kobolds, but not completely, depending on your definition.
