Ok, I see. The top-right might be somewhat usable but there the size is somewhat of a problem.

A larger image resolution is always good – it can always be scaled down but you can’t scale images up. It would be especially usefull for the character-badges since they are pretty small now. Nowadays even mobile phones are coming with FullHD (1920×1080) resolution so you could double the height and width and it would almost fit on a portait screen. But of course – at the moment I think it’s more important to extend all available characters… before working on new resolutions for the images.
