I have a new form for commission requests that covers all the specifics and should make the process easier.
You can get it through this link: https://goo.gl/Lb7NJR
Fill that out, send it to my email at email@example.com and I'll get back to you as soon as I can. You can also just write out your responses to the questions in an email if you aren't able to fill it out by hand and that'll be enough.
Shoutout to https://artofjess.com who allowed me to make a variant of her commission form. Go check out her awesome work!
