Thanks Zilrion for the PO, and thatnks for the comment Janos
So I started working on the 8 of pentacles. Here's the card descrip: http://www.learntarot.com/p8.htm Basically, dilligence, hard work and attention to detail is the meaning. Since it's of the pentacles (earth) suit, it usually has to deal with crafting. It was pretty hard to think of anything better than "alien repairs something" but eventually I came up with the idea that the development of those super-efficient chlorophyll plates I was talking about could have possibly solved an energy crisis they had in the past. The image turned into a dedicated scientist working to develop those plates. Here's where I'm at and a short description:
“We faced the sixth energy crisis in the same amount of decades. Fossil fuels were finite, fusion was impractical at smaller scales, and our entire way of life - made possible only by our power suits - was seemingly coming to an end. Mran Dalla refused to lose concentration, however. Her diligence lost her her friends, her mate, even her status as a scientist. In the end, she developed a new molecule called atraphyll - an incredibly efficient, nearly black version of chlorophyll able to absorb energy from even the green portions of the EM spectrum. Weaved onto standard energy plates, they powered our suits with ease. She drew her inspiration for the earth, and we all draw our inspiration from her.”
Unfortunately, the story turned out to be more interesting than the image. Here are a couple of sketches for it:
I changed the pose slightly after realising that it wasn't very natural. Any crits or ideas on the miage are appreciated. It'll of course be better once more rendering and textures get in there, but I feel like something's missing.
