Got a home spun feel. I like the overall feel. The colors are really nice and feel like anime.
Is this for the backside of a jewel case album cover? If so, it's appropriate to have track listings. There would be certain things you would want to list. It's not common to list tracks on the front. But if it's a promotional piece of art, it's nice. You would want more personal info like how to be contacted and so forth.
But that's all mechanical stuff (all of which take up space) that you would want to consider when you finally get into it and clarify the use of this including it being something of an introduction of who you are to the world. Are you a solo musician? What style is it? What do you play. . . etc. There are several ways that info can be conveyed. But any time you want to approach a visual communication but of art, it needs to be thought through all the things you want it to do for you. This looks like a mighty good starting point.
I do like the mood. You have a lot of good stuff happening. Best success with it!
