That archon is way overpriced for what you're giving her.
Should be 80 points with that loadout. (unless you're just adding the venom's cost to her, but then listing the venom's cost a second time) Which puts you at 1005 with the archon's points being corrected.
The rest looks good, I'd say the weak link in the list are the 2 Taloi - as they'll find it difficult to keep up with the army.
They do bring some decent sustain to the list though. However, they perform best when in close combat and it'll take them a while to get there and its not that difficult to just keep avoiding them. However, you do want to use them as area denial anyway, so that may play into your favour.
The new necron codex is pretty crazy against our shooting though (especially our splinterfire). You'll find that razorwing's 4 missiles might barely even kill anything after all those armour and rerollable RP saves are made.
I played a game against the new codex recently and I think the only unit I managed to fully wipe out was one tomb blade squad to regular shooting. I then got a unit of reavers to surround and glance a ghost ark to death and wipe out the warriors inside as they couldnt be placed on the board.
Otherwise I just tried to stay away from him and go for objectives, they are almost as fast as us now, and the new wraiths are brutal. Their ranges are still worse than ours at least, being a mostly mid range army. But a big Veil of Darkness deepstriking Immortal's unit is pretty crazy.
You can't even tie them down in combat because they can just deepstrike out of it. You have to hope for a really bad scatter to be able to stay away from them. I've seen that unit with an overlord to tank the shots as well as a cryptek, both carrying a res orb - so two phases of rerollable 4+ RP saves after their 3+ armour and the overlord's 2+
