I made beta Suicune~! I based the colors off of Suicune's shiny form and the pose off of Suicune's Gold and Silver artwork~
For those that don't know, the group behind the Cutting Room Floor site has found and dumped the ROM of the Spaceworld demo of Gold and Silver from 1997, which was a year after development started but two years before release, what you see is actually Suicune during that time.
