These are a couple things I got into the Student Art Show at my school.
above: Actually a 18"x24" poster, so a lot of detail was lost when I resized it to host it. There were about 800 shapes in this sucker. Done in Photoshop with the pen tool. It's 24 inches in width, but I cropped it because most of it is negative space on the left, with the chord going out for another 12 inches or so.
above: a 11"x13". Again, a lot of detail lost, but it still preserves most of it on screen. Done in photoshop with the brush tool
