Yes, definitively! You need more pokes. And all characters must go on move. I use to share some ocs with Friends and keep them together. All of it for free. I use to have tons of ideas ;_; and be in love of a lot of chars so I know it can be hard.

Also, congrats for sales!

Hehe thanks~ ^^ and I see~

Honestly, I say keep the first one. They have such a wonderful colour scheme, and I see a lot of potential with good art. They just need a little refinement and touching up, such as possibly an anthro form and outfit. I definitely think you should keep that one, but that's just me. I tend to get an attachment to most of my characters/OCs

I actually just got an anthro form for him~

The answer is rather simple for me.

Do you enjoy playing with them? If yes, keep them. Otherwise, you might as well sell them.
