Same boat… But I had some success with low poly 3D models which I found are pretty easy to make. Learning a bit about color theory, how to match colors, as well as learning a bit about level design goes a long way. You can make a great looking game this way.
But my dream game is 2D pixel art, and I really suck at it.
And also, you can sort of brute force things to look good it with shaders.
