Wow, awesome painting. I love how perfect the colors came out. You can really see the detail at times, too.
As for the PNG/GIF argument...
Those are pretty valid points, I guess... but you can choose your colors with PNGs and unless the people you're targetting are still using some old outdated IE, they should be able to load PNGs with no consequence.
As for the filesize... again, you can lower the color count on a PNG to be the same color count and even palette as a GIF, and it would end up having a smaller filesize than a GIF while having all the benefits of a PNG.
I try to use nothing but PNGs now, heh. I used to do what you're doing, but that was quite a while ago, back when Netscape and older browsers still mattered, etc.
Now, with Firefox and IE6, there's really nothing to worry about in terms of images. If your target audience is still using Dial-Up and still using an older version of IE that doesn't support PNGs.... then I can see your points.
