Here's some of the artwork I've been producing for various online games. They're all quite small in size, and have to be produced fairly quickly. Sometimes I work double the size, to have a bigger version for the portfolio, but if time is short I have to work at actual size. I'm usually just given a title for an image and everything else is up to me. They're a lot of fun to do, especially as I can do what I want with them.
The last 'Sea Battle' image is a rendered image. I modeled the ships in Maya (initially only modeled for icon images, so no great amounts of detail) and rendered the image with Mental Ray. I composited everything in Photoshop with added elements, such as the sky, sea, gunfire, smoke etc. I love doing these 3d-2d illustrations, they're a lot of fun.
