Troubles with Trellis 2 Comfyui.

Hi everyone, I recently discover the joy of AI generation, and just started to play around with comfyui. Basically i dont understand 90% of what i'm suppose to do. But to describe briefly what i'm trying to do, I've created a picture a friend, in a style, or kind of style, of a bobblehead figurine. Also generated the back render of it. I'm trying to creat a 3D high details model using trellis 2 in comfyui based on front and back view.
