I'm gonna punch myself for doing this.
I'm bored, so post a picture or PM me or something of your in-game blockhead,
and I'll make a small-ish 8-bit version of it, like mine.

2. Make sure I can see the whole blockhead, not just the head.
You can hold an item if you want to, I may or may not put the item on the avatar though.
Here's a template if you want to do it yourself:

Ones I made so far:
