It sounds like you are not at a meeting of the minds with whoever is critiquing your mix. If another engineer criticizes how you're mixing without offering a solution then you should re-evaluate their motivation for telling you their opinion.

If it you're happy with the sound then the next time he critiques, ask him directly how he'd solve it and move on.

If he's your boss, then he'll want you to solve it and keep moving. If he is the client, then get a reference track. If he is a colleague, ask yourself what their motivation is and move on from there.

Also, it sounds like you're doing a lot of processing. In the future if you're relying heavily on saturating individual drums, you might want to run that effect in parallel so that the clean image is retained as other instruments are added.
