Some of your items (it's inconsistent, but there are a few) are using the horrible looking model known as builtin/generated which was commonly used in 1.8.9, but doesn't look like normal items, and it makes items using it feel out of place.
This toasted core is using said model (item: fp:spaceship)

However, the E-Scanner is using the proper model (item/generated or builtin/generated with the transform forge:default-item)

You can see the difference being one is being held like a shield, while the scanner is held as a normal item.

ok mI have fixed in int toasted ram, toasted chip, and toasted core, have you found it anywhere else ?

I think those were the only ones, but I haven't progressed very far in the mod.
