I do not have the time to animate such a long animation, i could do 5 seconds at best... That being said, if you wanted this to have the homestuck style you easily can do this yourself, there's enough sprites of the homestuck characters to do this animation without drawing(except for june), you can see how in homestuck they overuse the laws of animation: slow in and out, anticipation, arcs and exaggeration; without modyfing too much the usual sprites.

I can see in the animatic you have skills to pull off things without resources, it is very clear what is trying to convey, the action is easy to understand and I love how it is written, I think it would be a perfect introduction, if you need help taking it by your own hand I can help you totally
