Pixel Art Feedback for my Dice Roguelike

I’m working on Dice Roguelike “Cluiche Disli” and would love some feedback for my pixel art.

These are art for various items that you can use in the game:

I’m currently using Aseprite and am very new to pixel art in general, so any feedback is appreciated
