WOW! Even with subcontracting the dig and the cement you did a ton of work... and it's beautiful

. The diagonal stone path took lots of extra cutting but looks fabulous and is a testament to your craftsmanship. I have a 100% DIY above ground pool that is nice but no where near as elegant as your setup. I really like the pavers all around. I think I'll steal that look for my walkway (which is still grass with drainage ditch

). And a diving board to??? Dang! I'm only 52" deep and can't even contemplate a deep end.
Did you do the design or get some help? If you used an existing pool layout plan then where did you get it?
If it's handy I'm sure folks here would be interested in seeing a price list breakdown for materials, rough labor times, and overall cost per feature: excavation, steel & concrete, liner, plumbing, pump/filter, fountains & waterfall (excellent touch!), deck pavers, round platform, retaining wall, sunken eating area (steps & stones & lots of labor shaving & setting!), Grilling island & paver path, ...
I know from 2007-2009 I've spent about $6,100 building my 12'x24'x54" AG with 160'
2 solar heater. ($400 site preparation, $4,000 pool kit+ (frame&wall,liner,pump,filter,ladder,misc.), $250 plumbing, $450 solar heater, $1,000 deck/solar heater roof.) From your rough ~$12,500 comment you got a ton of value for your money and effort.
