Bryan,
Hey, it all looks good to me.
I suspect that these bunkers somewhat emulate Thomas and MacKenzie. Lots of us are doing these type of bunkers recently, and if these were done by C and C (and they are similar in style) this board would drool over them like they were some kind of sacred cow (oops, wrong thread) and say maintenance cost be damned! By HF, they start out as copies, too expensive, etc. Sorry, I couldn't help but point that out!
The top hole has center bunkers and lots of options. The right fairway could be a bit safer than it is, IMHO, and I question the steep bank cutting across the fw and the short right bunker that seems like a top shot bunker. The little pad of fw just ahead and just beyond the shelf and short of the "spectacle bunkers" just don't look like viable options compared to the left and right fw's.
And, if they were worried about maintenance costs, taking out the wide center areas that aren't options would reduce turf by an acreage on this hole by about 10-12% which would yield savings. The top side of the bunkers appear to be fescues which, if not overwatered by the irrigation system, shouldn't require daily maintenance. Having part circle heads above the bunkers, or proper spacing of full heads to not apply water here is a key to making this design work.
As to the wall of bunkers, I like it - if a shot is blind it defines the edges of the target areas for the golfers. And it its uphill by virture of a golfer declining a risk on the tee shot, then if it scares the bejeezez out of them, its just reward.
While they are probably seeking a consistent style, if they had three or more of these design situations, I agree they might have made the choice to make one of them a big sand area, one a grass bunker, or whatever. At Devils Pulpit, they put a sod wall bunker at least 20 feet deep in the middle of a par 5 fw, and I remember that one to this day!
