I'll give this a go, standard disclaimer i'm not an authority on anything, just giving my opinion:
1) Centerline bunker probably a touch too big, greenside one as well. Give some more room on either side of the fairway. I would move the tee back quite a bit as downwind i can just carry the bunker with the 300 driver. Also not sure strategically why I would ever play left of the centerline, might watch some b101 videos on green sloping to give incentive to play to eitherside given the pin.
2) Sculpting here a little harsh especially with the waster bunkers and cliffs. Also might think about scaling down the trees as they're pretty giant. The base size on trees is often pretty big and it's usually best to shrink them instead of scale them up. Don't mind the green here.
3) 90 degree doglegs are usually frowned upon unless executed very very well, not sure if this is meant to be drivable, I barley missed but think I could get it pretty easy. Don't mind the green slopes again.
4) Like the tee shot here. 2nd shot you probably wanna be able to see the back bunker behind the green from the fairway it's pretty harshly scuplted.
5) Fine with the tee shot here, same comment with bunker sculpting and visibility. Green a little on the small side for the amount of slope it has.
6) This is very downhill and pretty far away from the last green. I would try to route your close much closer from green to tee and that will help save on planting. Same comments on sculpting
7) This green is too hard to hold imo, might soften it up a lot. Same comments on sculpting.
8) like that you're using diagonal hazards, but this is a stark departure in bunker style, and more Pete Dyeish than mackenzie as you stated. Also might look into what reward you get from carrying either side of the hazard, there isn't much incentive to take on the right side of hazard with green angle and slopes.
9) A shallow green should generally be reserved for shorter iron or wedge, and definitelty not a 3 iron approach. Not sure this one works.
10) unintentional blindness if I don't take on the super narrows is a little harsh, same comments on sculpting here.
11) Front bunker here looks great, this should be the standard of bunker sculpting on your course. Try to get them all to this level. Green here needs more, it's very flat as is and a little boring for such a short approach.
12) can carry all the trouble off the tee move the bunkers back. (these bunkers need some love and aren't of the same style)
13) green very very flat here, same comments as 11 green.
14) forgot to type my comments on this one, think it was okay.
15) amp this green up a little more for a short 4
16) very flat green again
17) ""
18) This hole didn't do much for me strategically.
Overall might go for something easier than a mackenzie style course for your first one. Focus on routing, hole strategy, and playability. Go check out b101 golf on youtube for strategy and some more advanced concepts. On the technical sculpting stuff the crazycanuck tutorials will be your friend there. Good luck, and hopefully that helped a little.
Go check out Del Monte Heights, Black Oaks, or Stillwater Point (warning very difficult) to see some of the mackenzie/costal cali styling done very well.
