1750 Tyranids thoughts?

[R4G3]

Hi I am going to a turnament soon and have made a LVO inspierd list sinse I like the way it played out! :) So I was wondering since I had to cut off some things, that I may be missing some key units, or if I shuld switch some out?
Some FW moddels are not allowed, but I still got to use a Malanthrope! :) So but im still not allowed to use for example Barbed Hierodule as a low... :/
