You convey a lot of personality through her pose and expression. On guard and nervous. Also, very cool design on the shield.

Out of my tabletop characters, I think this minotaur cleric would suit your style the best.

Ratlings getting into shooting competitions with fire warriors.

Everyone remains a good sport, so long as the ratlings remember to keep their sticky fingers to themselves.

Very much so! Seems very affordable and it would play well to your strenghts of playing with shapes and colors.

Maybe batches of singed fur/darkened hair tips from when she's gotten lightly scorched by her own explosions? Hair would probably be tied back during work hours for safety, unless she is the reckless type?

What kinda changes were you thinking? I feel she already has a really solid design. Simple, but distinct.
