The hazardous cursors look great, I hope you'll find time to finish the set. I also wonder whether you would like to make them multi-resolution to please people running Windows 7 at 144DPI? Since you have the 3D sources, it should not be too hard to render them at 96x96 and during conversion selecting 32px and 48px - Windows 7. 96 is 2x48 and 3x32 so, the quality should be perfect for both sizes.
