For the Hive Tyrant, get another gun instead of the Scything talons. Any gun but the spinefist will do. The TL-Deathspitter helps him crack open medium to lightly armoured vehicles (most skimmers) which can really help support your assault'ish army.
The leaping warriors need Rending claws... The rending ability will greatly increase their effectiveness... You don't get many rending claws on the new warrior sprues, so consider using the genestealer ones if you have extra. Also, I would drop the fleshborers and get scything talons, since if they are in range to shoot, they are in range to charge (unless you shoot and kill the units in charge range).
The Lictor is tricky to use. He can make a great fire-magnet if you deepstrike him in hard cover, especially if he is under synapse control so you can't take him out with 1 shot.
I can see you are using your guants as cheap assault gaunts, with the extra I meaning they can strike first and last longer in combat vs most other units. It could work. Best to try out 2 different guant squads with and without to see how they do compared to each other.
Hormagaunts are a bit expensive, but at least they can hurt AV10. I like them with just the extra initiative since it's rare that they won't have another target other than an AV10 vehicle.
Swarms are cool, but slow... Consider giving them leaping...
I don't like scything talons on genestealers. I'm a big fan of getting extended carapace and scuttlers, though most people think that's too expensive as well.
The Zoanthropes should get a 2nd hive mind power on top of warp blast. Most people get synapse.
Close combat carnifexes can often spend the entire game trying to reach the enemy, and the points there could be best used somewhere else. They tend to do a lot more with guns. I do use a CC carnifex (2xscythingtalons,+1I,Fleshhooks) but he's cheap, and acts as a shield for my advancing leaping warriors since he blocks LOS.
Yeah, that's a lot of models to paint! Read the last few posts and you'll see someone talking about the dipping method using minwax. Looks good and it's quite fast.
Also, if you want to go with less numbers, use more expensive models. Get a flying Hive Tyrant, get some Ravenors, get more genestealers and less gaunts. I have a 1700 point list with 2 Hive Tyrants, 2 Carnifexes, and only 40-50 more models.
