If you're concerned about being a copy, perhaps some improving is needed. It isn't bad to take inspiration from another persons work so long as you're not purposely stealing it. There's a lot of people who flat out use the style of simplistic character designs even before James started odd1sout. Hell I started putting my comics online because I was inspired by Domics myself. I will say this, in order to stand out you probably should try to make your work something that is different from anyone else that uses that same style. I read the odd1sout because I can tell the creator loves what he's doing and he is very clever with his comics. It's honestly up to you how you want to stand out and not have to feel compared to the odd1sout, domics, or jaidenanimations.
Good luck on your personal endeavors.
