Well, if you can draw, you’re halfway there! Next you need to learn animation. You can animate using Flash (recommended), Anime Studio, or Photoshop. Photoshop has a Save for Web feature that lets you use GIF format, but I like using Flash’s Publish as…>Animated Gif (don’t use Export>Movie…>Animated GIF, that lowers the quality by using too many colors. The Publish feature has more options and yeilds superior results.) Make sure your GIF animation only uses a few colors, that will keep the GIF’s filesize small enough to actually view and keep it looking super smooth~ I hope this helped!
