Commissions are tentatively open. Message for details and a quote - sketches start at $3. I have no idea how to price things.
I take requests on rare occasions. Now and then I'll open up freebies - usually there are 10 slots available for these when they do come up so always stay tuned.
Trades are things I take on a sometimes basis - usually if work or other commitments don't have me too bogged down. However, it never hurts to ask. When it comes to trades, I accept trades from people of all skill levels.
