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
Just fill that out, send it to my email at firstname.lastname@example.org and I'll get back to you as soon as I can. I also formatted it so you can write your responses to the questions in the email if you aren't able to fill it out by hand. Just provide the answers number by number 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!
