Feeder tendrils on something that already has WS7/WS6? Really? No. Drop that from the Broodlord and Genestealers, it's not worth it, and will never have an real effect. Also, I'm a big fan of Toxin Sacs on the broodlord, because it's not expensive, and wounding MEQs on a 2+ will be godsend.
Genestealers are best kept vanilla, as you did with troops, except for with Broodlord, where you need to give them EC, and nothing else. Broodlord+Retinue will take an assload of fire, so if you upgrade them with other stuff it's both unnecessary (show me any unit that can survive a broodlord and big unit of genestealers charging it) and will give your opponent more points for each kill.
Hormagaunts are best kept vanilla, because they're only there to die and to tie up the enemy. They will never be as good, points-for-points, as genestealers in combat, so keep them as cheap as possible.
Gaunts are good vanilla as well (meaning just with a weapon, fleshborer being the best). Without number is a great upgrade on paper, but when it comes down to it, it's not much use. You have to have your entire unit destroyed (which will not happen often, and when it does only very late in the game), and then they come back from your board edge, which means they rarely will get to do anything expect maybe capture objectives.
Warriors are okay, but would benefit from Toxin Sacs. Also, since they're going to be close to the enemy anyways, I'd highly suggest Rending Claws over scything talons. There will generally come a point in every game where you run out of good targets, and the rending claws helps keep the warriors killing.
Lictors suck. They come out in a bad place, don't do much damage, and rarely can survive strikeback from whatever they charge. Put those points elsewhere.
Good choice with raveners, but I'd suggest splitting them into 3 broods, 2/1/1 split. The worse targets you give the opponent, the better.
As for the carnifex, I'd suggest a sniperfex.

Overall, the list is decent, but you're really lacking in synapse. Only 3 sources, one of which works like fast synapse due to infiltrate, but also this means it won't be able to hold anything with it at the start. So you have 2 non-survivable synapse sources to cover your entire deployment area. What you would benefit from is beefing up your numbers a bit, and picking up a trio of Zoanthropes. At 1500 points, a Flyrant is generally a better choice than a Broodlord as well, but a Broodlord is workable (I used it myself as my only HQ choice for about 4 months).
