Every image with the exception of the fire breather. I finished it, went to create an internet-friendly version, and discovered it was too small (10×5 vs 20×10). Since you can’t increase an image in Photoshop, and I ran out of time, I decided to stick with the three above.
Four was already overkill, so losing it hurt me personally but they still fulfilled the requirements, and then some. Overall, I’m happy with the results.
