Gandalf and Radagast in coffee

My 5th coffee painting is finally finished! I started working on it in January, and only finished now in July. I've spent countless hours on it because I didn't want to skim over any details. Here are some more pictures for scale and detail: imgur.com/a/3rllb

I've only used instant coffee and water. I hope to sell this, but not sure how, I'd like it to go to the highest bidder
