Thanks for the compliments! Glad you guys like it, I decided to try out a new version with a rearranged layout that makes it less cluttered:

I made the type icon a little smaller, mainly so it would line up better with the PP, though I guess it would also help cut down on the amount of tiles the type icons would take up in memory. I also changed the way the empty section of the health bar looks, I'm not sure if I prefer the way they look now or before though.
Edit: I updated the background a little bit and added a second version of the PP box with the written type instead of the icon. I prefer the one with the icon but I do like how the written one came out, it might not look as good with shorter types like grass or fire though.
I also just realized the background wouldn't look right on the color version, maybe something like this?

It actually looks better then I expected, I thought it might look strange having the grass in two different colors but it seems to work alright.
