Never Ending Card - Fun With Folds Swap

I used this tutorial (see it work here) to make this version.

I stamped the pink background swirls (I think it ended up very pretty) after assembling the pieces, then I stamped the red sentiment on the wrong side (ugh!) so my card opens in a different manner from the video. After the stamping, I added flowers and then put a dot of Matte Accents in the center.

I think it looks a little plain, but I don't know what else to add. I'm afraid if I add too much dimension, it won't flip/fold correctly.
