Nice job on the deck - I especially like the interlock patio with the "easy bake oven" in the corner.
I've never been a fan of lattice to close in the bottom of the deck. When I had my deck re-done last fall, using a composite material, I used the same material, vertically, to close in the bottom, but my deck was a bit higher off the ground than yours.
With the height of your deck, I'd be tempted, on the side next to the poured cement walkway, to build a full-length step (or two) depending on the height off the ground. Then on the front on each side of the step and on the right hand side (opposite the walkway), I'd put in some low shrubs to cover the space. Just a thought.
