I never did a landscape before, so here's my first attempt at it. It's a quick sketch (~1 hour) of landscape from the game Halo. I remember playing that game in 2001 and awed by the spectacular scenery.
Could I use it as a Background for an picture?
Yes, you may, as long as you adhere to the conditions that 1) you post the due credit and link back to the original image 2) that it used ONLY on deviantArt.
Reminding me of the sense of disorientation I got when I first played the level "The Silent Cartographer". I miss those days.
