I am using my 100th post to restate that the Empress KGB middle background is too similar to the shade to the Panda's legs. This is based on my experience from selling half a million USD in custom neoprene mousepads over the last decade.
I'd recommend making the darkness of the middle portion lighter. There's a risk it comes out the way it looks in my photo below. At the very least you could ask a graphic designer about their opinion.
I'd have these printed myself but the largest sizing I have is 28" x 23".
