About 5 years ago, when The NSider Forums still existed, I was always contributing to their art contests.
When Sonic Gems Collection was about to release, NSider Forums decided to do an art contest for the game. Now back then, I didn't have a scanner nor did I have Photoshop, and all I had at the time was the standard MS Paint. I worked with that program for years and I felt like this was my best piece I've ever made with the program. The signature is "S2M" which stood for Sonic2Mario, as I was known in the NSider Forums.
