I sketched out some quick, unreferenced ideas on how the requested pegasus piece can look :3 Let me know which you like, or if you don't like any XD

Here are the main ideas I came up with, as numbered on the image:

1. Simple picture of the pegasus standing
2. Chibi pegasus XD I drew that one mostly for fun, but figured I might as well see if you'd like it XD
3. Action shot! It might be hard to make out in rough, unreferenced form, but it's basically a more unusual pose than in choice 1
4. Combination of the pegasus and dolphin requests XD I don't mind drawing two separate pieces for the pegasus and dolphin, but if you want to see them together for artistic delight, that's great too For this one, you can pretty much choose any style of the first 3 choices to use.

Let me know what you think, or if you have trouble seeing the sketches for any reason!
