I love the lighting and colour! It's funny, your work always seems to remind me of what my work was intended to be like (animation and comics, etc). Thanks for the inspiration and for reminding me I should get back to my art.
It's a shame that the game never came about... these concept pictures are really lovely. I think I would have loved to play it just for the beautiful background images. ;D
I love how you use the fisheye perspective. It lets the viewer experience the room as a whole. And I really love the light pouring in through the doorway. I get this warm feeling from your color choices. Very well done!
