looks mint....couple of things...
oil catch can is venting to atmo = not legal..
.in fact im a bit confused by your setup..it look like it has one pipe going to catch can and other going to turbo inlet..if thats how it is, its not right...Both cam cover outlets should go to top of oil can and your "atmo" vent should actually be venting to your intake
also you have a thermostat on your oil cooler I assume, or your oil is never going to warm up..
Wideband sensor is usually recommended to be further downstream than the dump closer to the cat as the high temps in the dump can burn them out quickly..
I see no carbon canister = not legal
i would use black silicon joiners not blue, for extra stealthishness....
where is your window washer bottle ?
and how did you get that cooler pipe so close to the fan?, my sits way higher than yours and almost hits it...
All that aside though Its a top job mate, it looks very neat and I'm a little jealous
