Sure you can! Just make a list of things you really like in a male/female (whatever gender your oc will be) and personality traits you love! Then either commission it or draw it yourself! ^^
Give them something that makes them special if you'd like as well. Kinda like how my Serena is a Frost Mage. You could pick something like that, Doesn't even have to be something fantasy if you don't want that.
I think you could do it if you just put a little thought into it (: Just grab inspiration from other artists and pick out things that are interesting to you. Looks like you like Nekos as well so that could be a start :3
