Looks fun, lots of stuff going on too look at. Line and shape-work can always be better, but that should be a matter of time.
One thing i think could use some attention is the color levels and contrast. Cause it might be fine when looking with a crisp display under ideal lighting condition. But in my case (kinda shitty phone with daylight) things can be a little hard to see, like the charactere legs and the trees on the left and right. Might be handy to turn the image in black&white/grayscale then see if everything is still as visible as it should be.
Cause there's clearly some effort put into the background as well, shame if peeple have a hard time seeing it.
So I'd either make sure things stand out a bit more from eachother, when it comes to colors, brightness or contrast & all that jazz. Or either simplifying some background elements so its easier to differentiate things by their shapes and silhouettes.
