Sketches! Also sketch commissions? (NSFW) (Patreon)

I'm thinking I'm gonna add a sketch commission tier to my commission list, but I'm not 100% on if I want it as a fixture. Gonna test drive it to see how it goes, so if anyone wants a sketch like these, right now they're $25! 

The first pic is Dana, nakedy as usual, the second is Bold, my old City of Heroes cyborg sabertooth, and the third is Gruff, 'reading' in the sun.
