The cutouts look great. Only thing I can think of is that the cupcakes look real but springs are kind of cartoonish in comparison.

There are some small cutout issues:

I'm even not sure if my first example is a cutout error. It just looks like one.

But I doubt that this is the refusal reason, because you really need to be a specialist to see that.

But I see a huge amount of compression artefacts. You can see them too really good in my second picture.
