Help please, I don’t know who else to ask. No one in my family knows programming. 
Can someone please fix my codes for me? I need to make the instrument a 3D object (so far I only did the 2D of it), and I don’t know how to turn it into 3D. Plus I need to create a person who’s holding the instrument, but I’m having a complicated time with spheres.
My codes are rather long, so I can’t post it here. Maybe I can just send it via e-mail to the kind-hearted person who will help?
