As of right now, the most I can say is that your team has good coverage for any type that your opponent wishes to use against you.
If you'd like some constructive criticism, you'd have to show what items and abilities you will have on your Pokemon, and you may also want to show the EV spread of each of them, but that is not 100% necessary.
Edit: It'd also be good to know if this is for Singles, Doubles, or Triples, and whether it's for one of the mainseries games, a fan game, or Showdown.
