First, always export as a .png file so that the background isn't filled. You should be using a proper vectoring program like Adobe Illustrator or inkscape, not a raster program like Photoshop or GiMP.
Second, check your work before posting, you have some areas that were not filled and the purple background color shines through in places it shouldn't.
Moreover, the two mouth parts do not line up properly and it looks janky.
I also circled many points that should not have a node. Those hair lines can be done with just 2 nodes like how I did on the left, otherwise it looks blocky. You did the lock on the left properly, so do that with all of them.
Same with the eyes. If a line is smooth, make the handles (bars) of the nodes align.
Lastly, for now, export at a large resolution so that people can use them for whatever purpose they want, they're called scalable vector graphics for a reason, and do not stretch the image.
