1) Your opener needs a lot of work. Instead of spamming FB for the first 7 seconds, a more optimal way to open on fights is to do something similar to...
-4s Pre-pot > -3s Pre-cast Ebonbolt > Flurry > Icy Veins + Ice Lance > Frozen Orb > Frostbolt > Water Jet > Frostbolt > IL to infinity
This allows for maximum usage of EB/FO/WJ, and gives you a solid amount of FoF procs to pad your IV uptime. There are two small risks to overlapping the waterjet and frozen orb, that being if your RNG is godly, you'll possibly munch a FoF proc from frozen orb and if you proc 2 brain freezes off the FB you'll munch one. Luckily both those things happening is about a 1/100 chance statistically, so it's a pretty safe bet.
2) You look to be munching A LOT of empowered Ice Lances. If you're at a point where you're just spamming FB and you get both a FoF proc and BF proc, hit IL > FL > IL. There are quite a few points that you seem to just hit FL > IL which wastes the FoF proc (since the IL is already empowered after the BF proc).
3) It looks like you're losing out on a couple more FoF procs from Water Jet. Wait until you have a FB cast at ~75% then hit WJ and start casting another FB. The first one will hit as the water jet starts the cast and the second one will hit before the end of the cast, giving you 2 procs of FoF instead of one.
4) Tighten up usage of Frozen Orb and Ebonbolt a little bit. Most of the time you were fine on the cooldowns, but there were 1 or 2 that look delayed by about 10-15 seconds.
5) You took Arctic Gale as your tier 6 talent but didn't cast Blizzard a single time. Blizzard can be pretty useful on some fights for reducing frozen orb cd and inching out a bit more damage, but Star Augur doesn't really have enough adds to warrant taking Arctic Gale over Unstable Magic, especially if you're not going to cast Blizzard.
6) Consider using Mark of the Claw as your neck enchant of Satyr. Satyr is a tiny bit better than Claw on pure ST but doesn't translate at all to cleave. Considering every fight in NH has some form of cleave, it could be beneficial for you to switch.
I can't really tell from the logs (probably because I'm lazy and also tired) but make sure whenever you cast EB you immediately follow it with the BF proc and IL, since Blizzard has made it possible to 100% guarantee a shatter on every ebonbolt cast this way. Similarly if you have a BF proc, cast a FB before hitting flurry/IL as you can also shatter the FB which reduces the cd on IV.
Hope some or all of this helps you out. Feel free to ask any questions!
P.S. For reference, I'm an 897 mage and my average parses for H NH at ~87 across all fights as frost. So far I have been raiding with Prydaz/Shard, but I finally got Mag bracers so hopefully my parses will be going up 5-10% this week.
*quick edit* additionally, I'm not entirely sure why your guild chose to sit you for Guldan, as you seem to be holding your own compared to your fellow raiders. If you have any logs from Guldan attempts that you were part of please link them and I can give better advice for that fight alone. Otherwise, make sure you talk to the raid leader(s) and try to get an idea of why they chose to sit you.
