Love pocket pages, actually many of my photo albums include only pocket pages. Here's my take, full credits in gallery. Have a wonderful day my dear!
I'm not sure that the upper right section still looks like a grid but I laid out boxes to help me figure out element placement.
Since the template I chose only had 3 rectangles, I copied one and added it (going off of the top of the page) under the journaling cluster at the top left.
