Tadaa!
Some month ago I walked down a hill to an evening course on my usual school path and the lighting that day was so beautiful and inspiring that I knew I had to paint it some day.
I memorized the view and the feeling I had and after a month or so I sketched my idea on my phone.
This is the finished painting I did on my tablet PC.

1 evening.. some 5h I think.

Here is the little sketch I did on my mobile phone in the middle of a night:

I began making my final thesis!
I will make a game!!

I guess i'll make some thread on CGTalk or Polycount or something on the game progress.

Here is an evening concept of the main gate to the evil factory that the game takes place in.

I think i'll do something more.. A good idea that mr. kanja-otaku had from UST was to make her dance Gangnam style!

Had this image in my head for a while now.. Decided to sketch it out quickly..

Yo!

I got myself the Adobe Production Premium CS6 pack and decided to test out the 3d painting feature!
Did a quick random sketch.. looked like some little garbage robot -thing..

You can see a quick test of the painting here: http://www.youtube.com/watch?v=n-7b5GOZCJs&feature=results_video

It has weird white artifacts sometimes.. but you would mainly use it to establish main colors and sketch out the design, after which you'd switch to the 2D view.
