Better way of saying this sentence.

[anu009]

I am writing to my boss to get consent on a requirement document sent to our team to review.

i have reviewd it and it looks fine but before approving i want to check if he has reviewed or has anything that he thinks might have left out.

"
Do you have anything in specific that has been left out before we give the approval on this release.

Since specific is an adjective, you don't need a preposition before it to modify the word anything. Also, that sentence should end in a question mark.
