You could add some more space between the squares on the icons background so they're aligned with the selection highlight.

And
what happened that there's no text on bckgrd_1 and 2? o.O Anyway, it's wise to avoid using too much complex images on bckgrd_1 because it makes
the text hard to read.
There's absolutely nothing on bckgrd_2... Put something in there.

Also, you could add the self-credit
where the file button is on bckgrd_2, since it's normally covered by the button on the DS so it doesn't disrupt the flow of the theme, while
still being there if the person opens the image before putting it in their cards.
