Rejection

They are (scanned?) drawings that you cut out?

You need to crop until up to the borders. That's true for all the assets.

Marmite: your cutout is badly done.

I laid a thin green line of one pixel around your object. Everywhere where it is green, transparency starts. You see that the transparency is present even inside the marmite, where you should have full material. Around the handle you see a quite irregular shape instead of a nice straight line. You need to refine this.

In addition, the marmite is in grey tones and has very little contrast.

Applying the same green line to the cake gives me a much better image:

The contours are more organic, so the waves are correct. I think, however, that the asset is very unsharp. In addition, those textures could be considered an error.

The vanilla beans are also well cut out. Very often, people don't get sharp corners correct. Yours are well done.

I think the vanilla beans are too dark. And they are also very unsharp.
