adding second tier group of switches via MC-LAG

Hello i have a pair of 400 switches connecting via 2 x 10GB MC-LAG ICL - you can call this my distribution layer

then i have a group of 448D's which at this time are not connected , This is a new deployment. - this can be considered my access layer. 

My question is - how do i connect my access layer to my distribution layer in this scenario - i

Does this look correct?

Will this provide me with enough redundancy at the access layer?
