The instructions. These are a little different from the instructions in regular sets. They feature a background section on the building featured in the set and a small interview with the set's creator.
Parts 2. Look at all those Sand Green cheese slopes.
I see one Travis Brick, one Plate 1x2 w/ Arm Up, a bunch of 2x2 jumpers, some normal jumpers, lots of tiles in multiple sizes and colors, and a lot of 1x1 Round Bricks.
Can you build a frame, or frames, right away? No, but you should be able to make some nice terrain right out of the gate. (+5)
Is it below, at, or above the golden ratio? At retail price, at the ratio. (+0) (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)Does it have more than a handful of immediately useful parts? I'm not sure. There's a lot of small parts you can use, but there's also a lot of medium and large parts you might not use right away. I'll be generous and say yes. (+5)
Score: +15 (A). It's a nice set. There's a lot of Tan and Sand Green which you don't see that often. You could also make a nice building for use as terrain in your game if your looking for a slightly larger scale than the normal 7P.
