I agree with Adam...not sure I see anything that needs to be changed.
It appears that the land has enough movement and interest, and I think we're all a little bunker crazy here. Not every hole necessarily benefits from centralized bunkering, and although it's certainly not the most visually spectacular hole in the present state, it is certainly minimalist.
The funny thing is that I've played any number of holes at courses that are low-budget which appear similar in style and tone. Generally, these holes probably benefit from not having much money to put into design and "accessories", yet provide much enjoyment nevertheless.
Yes, we can gussy it up with irregularly shaped bunkers, and adding fescue along the sides, and giving it more of a defined strategy, but sometimes, and I think in this case, it's best to leave well enough alone.
