It looks strong, a good balance on units.
A potential problem is superheavies and gargantuans. A single IK/WK will be practically unstoppable since there's nothing here that can really hurt that type of unit, which I realise is a major problem for any tyranid list that isn't tournament standard. Those hormagaunt units could hold one up quite effectively but if the opponent sees that tactic coming you don't really have enough bodies to stand up to enemy fire and still make it to combat with enough wounds to survive several rounds of stomp. A couple of big units of fleshborer termagants (or maybe more hormagaunts) would help out, and if you went down that route it would probably have to be the exocrine that goes to make space for them. It's a tough situation, and buying and painting all of those gaunts is going to be a big commitment.
In any case, it sounds like a new tyranid codex is on the way in the next few months so things could change a lot in that time. I'd be surprised if GW don't give nids a GMC in the new book, and if they create something half decent it will be a huge boost to a codex that struggles with the big toys most other factions get. If I were you I'd begin painting and assembling the models that you'll definitely want to take regardless of tabletop ability, and hopefully by the time you get through those the future of tyranids will be a bit more clear
