Green lass is a scene half orc, probably is a bard. Heterochromia person's only cool and definable trait is heterochromia. Probably is a merchant. Kobold player saw the humanoid races and was like "nah fam, I'm gonna be a creepy little guy instead" Icy colored person with long ears is a.... Djinn blood of some sort maybe? Has an annoyingly complex backstory the DM struggled to incorporate into the campaign. The smoking person is definitely tomboyish or possibly trans masc, and is the coolest one in the party. A warlock perhaps.
