This looks good! I can see your art style improving as you do more of these. Can I ask - What is the origin of your OCs? They seem to be a combination of Moon People and the Aliens from Sailor Moon R, which I think is very cool.
The origins were guessed at quite a bit but the basic rundown is:
Pinako Aino = DD Girl + Sailor Senshi
Daniel Kano = Myself + Both Sailor Marses
Katerina Suino = Toon Makers' Mercury
Val The Csar = An idea predating My going to high school, originally a multipurpose OC
Delphius = Toon Makers' Prince Darian
Narun = Naru with Morga's features
And the more recent reveals:
Anjiro = No discernable element, just a scribble
Kent Shinji/Shinji Kujaku = You'll have to guess on that one, but I'll drop one clue... it's possible for him to naturally be born in "The Incredible World of DiC" and a few other localizations, but impossible in all of the others, including Viz and the original Japanese version, where instead, he is a hybridized clone.
Edit: The Makaiju Aliens were not a source of inspiration
