Make Gamify Winning Animation Effects Gif file. Send samples of your best work.

I need 2 different gamify completion or winning animation effects with sound effects. I have some ideas but need to discuss with awarded graphic artist. Effects should last around 5 seconds each depending on the effect. Must have Transparent background. Gif effects must start immediately upon opening gif file. Must display perfectly on iPad Air 4th generation screens. All work must be 100% original. I will own the copyright to all images and sounds and content. I will own the source files. You will provide all source files to me.
