So while it's one of my few marketable skills, anyone up for some Photoshoppin'?
How it works is you give me a commission / drawing of yours, I'll play around with it in Photoshop and you pay what you think the end result is worth. I'm aiming for getting a nice round £5 each one but of course you can go higher or lower. I don't mind! Money's money either way.
Some examples of my own:

Camera taken photos of IRL stuff is a-okay! As demonstrated in the second example, you can still get some awesome results that way.
But yeah, hit me up in comments or notes if you'd like to take me up on this!
