Those look really nice, and with DT Swiss 240 hubs at that price you can't do better than that.
I do wonder why the weight isn't less than my XMIplay carbon wheels. Mine are 30mm wide with Bitex hubs, Sapim straight pull spokes, and Sapim nipples and weighed in at 1560g so I am a little curious that yours with DT Swiss hubs weigh 58g more, although that's not all that significant. For another comparison, my 24 mm wide DT Swiss XR1450 aluminum rims with 240 hubs, straight pull spokes, weigh in at 1450g.
Ignoring the weight, which is still very good, those wheels look really nice and should be strong and reliable. The DT Swiss Star Ratchet free hub makes a unique sound, mine tends to pulsate a bit.
