II am now working on the bios for my Trickery Treat racers. Willow is already finished but I'm currently working on Tantric but I also plan on having a mystery character after him. All I can give you is that is a female and a Halloween Icon racer. I might tease you with a silhouette image.
There are a lot more concept designs on the place such as the iconic pumpkin fields, the Pumpkin Spice Cafe, the joke and antique shop, Spellina's den, Willow's underground garage, the catacombs that holds the garage, the candy corn citizens, Dim Light's Reaper form, etc.
I also want to digitally paint my town square sketch since I like how it looks plus it's the center point of the island.
Original idea belongs to DreamerAwaken for her Sugar Rush fanfics, I'm just the design and addition to it. I might update my Sugar Rush racer, Tangerine Dream a bit and throw her in there ghost hunting or something. Maybe future stories in Trickery Treat would be horror and mystery with a bit of comedy. A FNAF crossover would be fun.
