Well, if you want to keep it as is then that's fine, I'm only reccomending it to you that you make the stem wider at the end and fix the lines.

try not to use my exact edit, cause I don't think you're allowed to but, use that kind of shape instead of a straight line for the stem, you could also make the leaf come out the front right instead of the back right sorry for the extra crits but you have an 2 imperfect lines also on the bottom lines of the apple. This is hard to explain but this is fundimental part of it, when drawing curved lines, you should follow a pattern such as 3pixels,2pixels 1 pixels,2pixels, and so on. In your case, with the bottom of the apple it has a 10pixel line, from that line left it should go 2,2,2,1,1,1,1,2,2,3,3,3 and the same with the other side. Man, this is probably the longest comment I have left, lol.
