Done in ArtRage 2. Reference is here: http://www.agostonl.com/kr/kitt4.jpg
My first ever take on a fighter plane. F-16 is a real beauty and my personal favorite. Had to research a bit before creating this scene. Done in GIMP using pencil, brush, spray paint and smudge tools. Took around 90 mins to finish this off.

Another one using tablet and GIMP. Took around 90 mins. Again a half baked idea but I think I am loving the tablet experience :D
