Game re-skin - Collectables

I've been animating the collectibles, for the re-skinned game. Given the context of the game, I made the collectables into poorly drawn treasure, but since that is really simplistic and easy to make, I decided to do lots of them (theres 18)

Starting with research, of course:

I just simplified those as much as I could, while brainstorming more ideas:

And here is the final sprite sheet:

I tried to vary up the shine animations to make it look more interesting, but it just made them all look messy - video game coins usually spin or shine in unison - I fixed that up on unity

The spining crystals and gems were the most challenging to animate - the crystals still looks a bit cluttered and gross with the thick lines, it doesnt give much room to clearly demonstrate how it looks on all angles - and I even got 3D reference for the gems
