Feedback would be greatly appreciated!
Personally I would be careful with the $195 /m for unlimited everything. But a lot depends on what your product is, how much your costs are increased when for instance a client with 50 users becomes your customer.
As @acedit said, it would be easier knowing what your product is.
It would be much easier to visualize it if seen on a pricing page.
It's hard for me to provide feedback without knowing your product and seeing how you present the pricing itself on the page.
Maybe Trello's pricing page could give you some ideas? https://trello.com/en/pricing
