Ok, so a few comments. I'm not going to make anyone change anything. I love them all. But you should be aware.
We have a Nomad Mystic and a Knowledge Cleric, which means skills are really, really covered. Both of them can be proficient with everything at one point or another. They both have such different skills that I don't think that they will step on each other's toes, but both of you are going to be "Oh, I can do that!", so you should probably work with each other to know who does what and when.
Second, a Ranger with the Sailor background. I love it. And it will actually come in useful in this campaign, since one portion of the explorable land is the ocean.
You have a Paladin Tank and a Bladelock, who is usually more of a striker but will have tanky capability. A good backup tank, if you will.
Though, if I would make any suggestions, it would be this: be a Tome Lock instead. The reason I say that is because you et proficiency with every weapon with just one level of Fighter, and you have no idea how useful it is to have those Ritual Spells. You are the only Arcane Magic user in the group. We've got three healers (which is insane, but probably good), but no other arcane casters. You're going to miss those utility spells, and the Warlock can learn all of them if they get the Tome. I don't see where you've picked your Invocations, though. Again, I'm not going to make you take it, especially since you're multi-classing, and therefore won't be able to do quite as much as soon with the Tome.
The Mystic is...sort of a replacement Caster? Depending on which Disciplines he takes. Nomads are more for traveling and knowing everything, but you could replace the combat Wizard, especailly if the Warlock takes the Tome instead.
Of course, any of you could take the Ritual Caster feat and become the team's Arcane Ritualist. Rituals are just something I've fallen in love with lately cause of their usefulness.
