Wow, so many comments already! The first thing I noticed is the thing that bugged me a lot when I was younger, even if it was stupid: The pokemon finally are further away. I always imagined the battles in my head and them being right opposite to each other seemed slightly stupid. I was a stupid kid, though, so to skip to the point I really like the distance between the both.
Then, I really like the background that doesn't just "stop" and fades out but has a horizon and Meritrot looks amazing.
I like it very much, detailed, but not too much to destract from the battle.... I always wondered, why they didn't make real backgrounds in the actual games... other than just floating strips of grass etc. Oo
Ah, I really like it. I've recently been getting Dew to take the same approach with my battle grounds. It's a lot better in the long run. I was stuck with just one battleground for about a year because of the style .
