It's quite good. Never do glares again. Ever, they rarely look good. But otherwise I think you could space out the legs a bit more. I like it.

I prefer the unedited. The purple haze does not go well with the bright sky, instead make the sky a lot darker then it'd look peng.

The animation is actually good. Swing the arms a lot more when he's running and a lot less when he gets back up from his fall.

No it's not. The window is blurred because the camera is focusing on whats in front not behind. In this case the camera is focusing on the raindrops and blurring the background. What @Pootsy35 is referring to is the abrupt blurriness of the edges of the window. Open the image in a new tab then zoom into the upper right hand corner and you'll see what he and I mean.
