I was trying to think of Undertale inspired commissions I could offer, and I went the simple route - I took the binary brush and just started drawing a portrait!
It's not "pixel art" per se, but I used the binary brush to get the edges to be hard pixels, rather than smooth lines with most brushes. Unfortunately, I drew this a little too big, so when scaled down it does lose a bit of its pixelyness.

I plan to offer these as commissions when I open next, which will be this Tuesday! Keep an eye on my Twitter and Telegram Channel for more info.

Enjoy!
