Yep, more detail needed on the construction.

You'll need to stop that getting too wet as grass has a tendency to pack down and you'll get anaerobic composting which will result in black slime - Nasty!.
Composted properly, that will be a very high nitrogen feed which is good for foliage growth but not for fruiting / flowering plants.
This would make a great step-by-step! It looks like you already have all of the photos- can you walk me through what you did?
