hello :) your OCs are very cute. i would definitely draw any of them (or more than one)!
i have a shop here for square headshots. you can see some examples there, i do a fully rendered type and a b&w type. i also do portraits that end more at the bust/halfbody, examples below. they aren't offered in my shop, but i am happy to do them for you.
for pricing, i work based on offers of pets or C$ from commissioners on CS, so if you are interested you can just PM me an offer and we can go from there!
