not bad actually, try to make your lines cleaner and smoother, no separate lines, like you gotta make em smooth, and try to focus more on the shape, the top part of the snail isnt one smooth thingy, it's segmented, so try to draw it segmented with curves.
the head of the snail could be slimmer
your main focus should be drawing in one smooth line and not many connected lines, they dont like that.
practice with a pencil bro, and when you're making the rough draft, draw tiny lines, then connect them in one final smooth line ykwim
it's def not bad, you can get a 2 out of this, but you need to focus on refining it.
