Here are the characters that I've designed for our senior project Which Craft, which is a 3D crafting focused game with visual novel elements. From left to right are our main character (Cady), and the three NPCs that we can interact in game (Beauty, Gentleman and Peach)
Their 2D arts & concept designs for 3D versions are done by me, and the 3D models on the right in the 2-3-4-5th pictures are done by Pelin Alvo.
