Heres a sketch/doodle i did during my free time, one of the most epic icon ever created. I cant wait for halo4 to reach here!
I guess i will probably finish this some day, SOME DAY.
Done in around an hour to 1.5 hour, a fairly quick sketch without any references, just sketching out my impression of the halo universe in my head. All painted except for the city-like lights and a very small bit of the clouds.
