Beginner List Help? 500 points vs Necrons

Hey all, I was hoping to get some feedback on this list. I’m pretty new to the game and I’ve never played Tyranids before.

My buddy who I’ll be playing against this week usually runs either Necrons or Thousand Sons.

Do you all have any thoughts, advice, or tips? I’m fortunate enough to have access to a lot of different models, including the recent Christmas box, so I do have other model options if there are better selections out there.
