Ceramic cup was made in low poly, materials used completely out of the blender.
As you asked for comment I want to say that your work is not bad, but you let a lot of files that is not useful to us, as the old blend files, renders and folders, that is making your file be too much heavy just for a cup. So I recommend you to clean your file, let just the final Blend file and a final render. Other thing is that you put a solidify modifier on the handle and this make a little defect in that, I suggest to you to apply the solidify modifier only on the cup, and let the handle without this modifier.
Your cup is beautiful.... you certainly have an eye for creating objects that are lovely to look at. Thank you for your kindness and sharing your craft....
