sometimes I like to make quick and dirty sketches that kind of communicate what i think is a cool idea rather than spending the time to craft a 'pretty' image, just to get the ball rolling on pitches for new areas/enemies/etc.
the first two images are early concepts of the ix. I thought it would be interesting to make it an actual array of rings to harken back to the ix symbolism... where the intersection of the rings becomes a Cosmic Eye. didn't end up going in this direction but i still think it's pretty cool.
last two concepts are set dressing for the raid which ended up being used, but I only had a few days to establish the visual direction of the raid environment. sometimes I like to start with player-sized objects and then zoom out to macro shots, sometimes the other way around.
