No need to be shy. I have never seen anyone laughed at because their work or because they ask help. I personally don’t care what the subject matter is, what it looks like or how it’s done, unless some of that is what causes the problem. Screenshots don’t have to be pretty either, just informative.
I understand why you would be reluctant to share the file and there are other reasons not to do so (work related, copyrighted material, licence issues, so on) or just don’t want anyone to see, which is fine. In that case it would cause extra work to get an example file but can be done. Could for example select the problematic part of the mesh, ctrl+i to invert selection and X -> delete faces, include relevant external files and save with another name. Then most of the model will be gone, just showcases the problem. All modifiers, helper objects, lights, material settings, world settings, render settings, and such are still there for troubleshooting.
Textures might cause a problem if their licence doesn’t allow sharing. Could leave those out if the problem is still visible, or try another texture. All of this fiddling might even reveal the cause of the problem while you’re preparing the file.
And yea, I still don’t think this will be solved without the file. Can’t even guess if it will be solved with the file but at least people smarter than me have a real chance with it. Outliner in your screenshot suggests that you have parented objects and modifiers on the thing but no idea what those are or how they affect the object and rendering. Could be a shadow, intersecting mesh, wrong modifier order. Too many to ask separately so please upload an example file.
