Just about everything here I have drawn myself using either digital or traditional mediums. I primarily sketch things with a pencil and paper, but I also enjoy painting in watercolor from time to time as well. Of course, when it comes to the content of what I make, it's primarily porn, though that's to be expected.
I will draw most things if asked (or paid) to do it, though I will actively refuse anything involving scat, urine, or vomit. Blood and guts are a go, just don't make it too brutal.
As for commissioning a piece, I urge you to check out my FA account as I have the prices set up there via the 'commissions' tab on my page, otherwise you can just contact me directly. I post all of my works that I think might not comply with Inkbunny TOS to my Pixiv, though I will admit I haven't read it very thoroughly.
