Hello Aeonscape

I am looking for feedback on my upcoming card game, Aeonscape.

The game mechanics are mostly defined, but right now I am looking for feedback specifically on the main art for the four different sets.
There will be additional art for each set, such as HP cards and character icons.

To aid you in the process of feedback, please note that the cards are representative of intangible concepts such as time and space, death and rebirth.
There are 8 different unit types, each re-imagined through two themes.

The WIP page is currently structured for feedback on the sets, focusing on different focus points.

After a month or two of feedback and redesign, a playable print-out version will be available to test the gameplay and general mechanics, and the cycle of feedback will start again.
