Old character, Theodora the eotyrannus. I've drawn her several times in the past few years, just never finished a picture of her. Eotyrannuses were covered in feathers. When I learned about them, they often were portrayed without feathers, I based Theo on that model, I really liked her design too much to cover her feathers. I also imagine her being taller than Laz the nanotyrannus and Relict the Nanuqsaurus (who are around the same height and size), when in reality she'd be substantially smaller.
