Newb hoping for some help

Hey I'm a total newb vibe coder trying to build something that's been in my brain for a while with Astra. I have blender / unreal / godot installed and we're making slow progress but the getting the models to match the charecter art has been a challenge. I've let it noodle on this for a while and this is the best it's gotten. Anybody have any tips on how to get to a more polished state? Different prompts? More tools? Or is it just not realistic at this point?
