It is actually very good art, keep it up! I’m also working on my art skills, so as a fellow artist, maybe if you have some time, you could check out the art in my game and tell me what’s good and what could be improved. Again, you did a very good job, keep it up!
One more thing, by consistent I meant in terms of pixel art resolution. This is a problem I’ve struggled with for a while. I think it’s called mixelation; it happens when art pieces are drawn in different resolutions relative to one another. Personally, I like to keep all my art relative to 16px.
