The banner is awesome for sure, the streamer is very coopl as well, but indeed it seems just a bit too heavy. I think it just starts out way too wide, giving to much weight to the top of the image.
I think if it would start with 2/3 or 1/2 of the width, it would be much better. And personally I'd make it even longer so it curls up to the rust sword sticking out of the ground.
