This was tough but incredibly fun. I spent about 5 - 15 mins on each thumbnail, trying to focus on the composition of the image. My end goal is to merge nature with the abandoned sci-fi technology in this images.
My references mostly consist of nature pics that i screen grabbed from Nat Geo and Planet Earth documentaries, and real existing buildings with funky shapes. My end goal would be to try my best to acheive a final look similar to the paintings in my Finish/Art References.
