You shouldn't convert to animated GIFs. You can't see it very well in that tiny resolution, and it's a massive file for the forums to try and download. Its much better to preview with a static JPG screenshot or something, and then give the link where we can watch it in motion.
That image, for example, is over 7MB in size.
The video is short, but nice. I'm curious: what contrast/brightness settings did you use when you edited this?
