Any recommendations would help

Yuor team is typinng wise balanced, but you got a huge weakness to fighting and a weakness to flying. You got those weaknesses covered in your movesets, so that's good.
Your team also has different pokémon with different roles, so your team is balanced.
This team looks perfect on paper, but you need to fight with it so that you can see how it does in battle.
