Are you putting 3 different logos into 1 item? Because that’s what it looks like, which could be a good idea.
Overall I like them, but I think you should adjust the logos in the last two mockups; the perspective of the logos doesn’t match the perspective of the page or scene.
You should also make sure to show the logos on their own without any mockup, just to show the customer exactly what they’re getting.
i do not know if this is coming from the mockup also but the fact of the matter is that this is looking really distorted and thus unbalanced in one side in two of the concerned logos …
