Here are the sketches I did along with the final paintings (that I didn't do) for Series 6 Postcards.
I did the concept and sketch for Maulboro and Neil did the final painting.
The did the sketch for H8 based on Mike Dantzer's idea (Dr. Sushi on the forum) and Matthew Kirscht did the final painting. (Not Brent Engstrom, as I mistakenly said). Matt did an awesome job.
Very happy with how they came out!
