Alfa I love the colours used, although they don't compliment each other, they are the colours of the energy saving scale. I like the work with the negative spacing in the leaf too. 🍃⚡️

Bravo I would make 'energy' the same color as pellet

Charlie The tiny bit of yellow overlapping the green at the top bothers me for some reason. Also not sure if the red area intentionally looks like an arrow or not. If not, maybe consider moving the burr on that side. Great work!
