Besides Tracks, TFMaster asked me to do some concept work a few times for customs he was going to make. Binaltech Huffer: He was converting it into a pickup. After removing the back, he was dting to know what it would look like after painting. Energon Dinobot and Terrorsaur: He had been thinking about making these for awhile, but wasn't certain how they'd look. Classics Cheetor and Tigatron: These were actually my idea. I mentioned once that I thought Classics Rodimus' face looked like Cheetor's. He imediately started making one. Right after stripping the flames off, he took pics and wanted me to do it up. Unfortunately, I had some issues with the stripes and such, and never got either one finished. I'm not sure if he ever finished the real one.
