Hello Mentis... I've played "Indigo Prophecy" as well, but yes, I know it as "Fahrenheit". :) Like you, I really enjoyed this game. Did you play it more than once actually? I've just played it once and somehow got the same ending like my sister. But I think there should be more than one possible ending. I was sad when the game ended because the whole story is simply exciting.
About your wallpaper. I can see that you wanted to put the focus un Lucas. I like how you placed the elements around him... the composition is really good but Lucas in my point of view stands out almost too much. I would have tried to maybe melt him with the rest of the wallpaper a bit more without taking the focus off him.
I hope you'll submit some of your own art soon again... I loved your paintings. :)
