I only ever vectored one image before, which was of Sho Minamimoto. Sadly, I don't have my first vector saved anymore—though I have seen it floating around on the internet a couple of times.
The above image was made with the help of this lovely tutorial. Check it out if you're interested in making your own vectors, as it's actually fairly straightforward.
The vector you see here is of Guuko from Mon Colle Knights. Sadly, you can't really find that series anywhere now. It's not subbed, and hardly any of the (cancelled) dubbed episodes are online.
