I really like your sketches. My spider senses detect some slight inspiration from Star Wars..... even Portal..... maybe. I always love random doodles, they have a carefree nature about tham that gives off a casual almost careless vibe. Not that your work doesn't look highly skilled and well polished but it looks like you easily sketched al this in the course of a day. That and who doesn't love random biotech and squids?? My favorite by far is the floating dome city with tentacles. I want to know WTF is going on in there. Keep up the good work my friend.
