the only thing that could be of concern is no guard for the tyrant.

he won't be fast enough to keep up with the hormogaunts so you have to be really careful with them.

you only have one synapse creature, that can be picked out so expect a lot of guns to be aimed directly at him.

and you have a close combat carnifex, which most armies will be able to dance around unless you can tie them up with the raveners and the hormagaunts.

you also might want to not try playing so many monstrous creatures in a 1000 pt list. yes they are powerful, but with you making them hth oriented you are going to have a lot of problems.

you will also find you have a lot of problems with skimmers. in fact the only thing in your army that seems to have a good chance of bringing them down is your bug blaster, and even he will have trouble doing it.

you might be better off with a shooty tyrant and making your first carnifex a sniperfex instead. because they are monstrous creatures they will still be really good in hth so you don't really need to worry about that, and you have the ravenors and the hormagaunts for close combat anyway.

also, what gun are your termagaunts armed with? you give us everything else but that.

oh, and you are breaking a major rule by posting stats. I would suggest you edit your post asap.
