Nice, text is a little pixelated. Your best sig yet IMO and I see you've improved in terms of colors. I'd like to see you try to make an abstract or realistic piece. And also, work at 2-4 times your final size, i.e. for 500x150, work at 2000x600 and resize. Also keep a full-sized version just incase. With my new laptop's Core 2 Duo, I can handle that. But my old Centrino had crashed countless times thanks to this habit.
