So taking inspiration off of Tom Montgomery's post, I'm going to challenge myself to produce one sketch per day for 30 days. I'm going to put 30 ideas in a bowl and pull one out each day. The only problem is that I currently only have 20 ideas, so I'll be looking for suggestions for the other 10. Just don't suggest Anime or something really obscure. lol. I'd like to stick with superheroes. I haven't really drawn anything in years, so hopefully Day 30 will be a vast improvement from day 1.
Here is the list I have so far. Leave a suggestion or two in the comments.
Alan Scott Green Lantern
One or more of the Thundercats
Old School Suicide Squad
