There is definitely a marked difference in the style of the alpha cards and the artworks being released now. Don't get me wrong, that is in no way negative. In fact, I think it makes the entire collection much more colorful (no pun intended). How boring would it be if everything looked the same? Exode art is growing and evolving.
Greens and blues are pleasing to my visual receptors so my favorite background art s the colony/farm with the habitat. I could see the plant image being the icon for a tech or something related. I have no idea what to suggest for improvement; I am always blown away by what the team offers. And to think these aren't even the finished, polished products!
Thinking... Processing... Perhaps more planet landscape art!
