Still practicing at vectoring. Anyways, here is my ponified version of Hatsune Miku. I don't know her cutie mark, though. Please ask permission first before using it. EDIT: made some teeny-tiny tweeks.
Umm can I nitpick a little? While it is nice it certainly has a few flaws. The right sleeve has a little extra line hanging off where the top top of the shirt meets the inside. The left arm's line overlaps the beginning of the sleeves a little bit. there are some sharp points in the lines where it looks like they weren't joined correctly. On the right arm's sleeve near the elbow it has a place where the inside color is devoid next to the line. Towards the tip of the hair at the end it looks like a chunk was taken out of the line. Other than that everything seems to be okay, and well executed.
