Model Painting Cleanup for Birthday Gift

I need an experienced painter to clean up a model I've created for my son's birthday. Most of it is painted, but needs touch-ups. This is a .3mf File that I have created in Bambu Studio. I need someone experienced in painting 3D models please within Bambu studio...
