May I recommend that you should make a game kit (just a small game like stuff in Craftpix (https://craftpix.net/categorys/2d-game-kits/) .
It is very suitable for someone who can code but have no knowledge of game art design (like me :D).
Just small game kit like a Word Game (Word Search)...
Lol, I dont mean that request you making a game template (I am a game developer myself, but lacking of design skill).
I means that you make a full GUI for a specific game like this one = https://craftpix.net/product/guess-the-flags-color-game-assets/
So people like me (know programing but dont know drawing) can take advantage of that (buy your GUI and make the game).
Br,
