Although I don't have too much time for research, sometimes I think it's a good idea to explore new things and find new ways of improving my renders. So, I'm giving you a few sketches I've been playing with. Environments, new lighting techniques, composition, visual effects and so on. I'm paying a lot of attention to the latest detail, so nothing is thrown in there without purpose. Notice the pink bus in the second shot, In the first image there's a new character I'll be playing with in the future. ;)
