Write now I'm working on a pet project and I'm at a point where I have to do a lot of art and it's all very similar; it's not inspiring and it's mostly depressing because I can see how bad I am as an artist very clearly.
you are clearly getting better. i know this for 3 reasons. one is you are doing it a lot. two is you are more keenly aware of what you don't like, so your awareness is better. and three is you are very fixated on wanting to be good, which is going to cause you to search for goodness like a gold miner in a gold mine
