I have a lot of things to say...
Mainly about the format you save your files.
First of all, one of the basic rules of saving is: Always use PNG to save your files.
PNG = PwNaGe
Gives better quality to the sprites you're making.

Also most of the berries are art from previous games right?
As for the Pokéball is a bit too flat.
The tamato berry just seems to have a lot of bumbs as how you placed the shading.
As for the overworld buildings, those are very... Flat. They lack shading, I know most of the buildings have not as much shading, but this lacks a lot of shading..
