WIP- Top Secret

Making a 2d character spin around is really freakin' hard. If anyone has advice on exporting gifs like this at a reasonable file size, please let me know. I exported from psd, and this 6 second gif was a little over 7 mb. The gif will eventually be 20 sec-ish long and be featured on a website so I'm trying to figure out the best approach to exporting so the site loads as quickly as possible
