Mobile Slider Menu - Principle Animation

Hello All:

Here is a slider menu concept created with Sketch and Principle.

I continue to experiment with Principle which I really think is a great tool. However, I am having difficulty keeping the GIFs under the Dribbble 8MB limit. This sometimes makes the animations look too fast or without proper pause as originally intended. If anyone has specific information on limiting the GIF size, I would love to hear more.

I am attaching jpg files as well.

Thanks, Gabe
