I was looking for a tool exactly like this a couple of months ago, for a starting point for facesets in an upcoming project. I so, so wish that this had existed back then.

This cute avatar creator is better than some random dress up game, with a nice art style and plenty of options, even including a base with Elven ears, which will be very useful for people using this for Fantasy themed projects.

If you do want to use this tool for your Dungeons and Dragons characters, RPG Maker games or whatever, just note that as of now, there isn't a huge amount of medieval fantasy style clothing. That's fine for most, and I don't think the goal of the developer was to make this a fully medieval fantasy style character generator in the first place, but perhaps some Knight's helms and Wizard hats wouldn't go amiss (and if those things ARE there, then please forgive me, because I didn't see them).

In all, I think this is a pretty great portrait generator, and people in the realm of pixel style games will get a ton of use out of it. Bonus points for being usable on mobile.
