You have C = 40 instead of 32.
I don't think it is good to have all of E at the outside.
Maybe this would be a bit better:

-CCCDDCCDDCCC-
----EEEEEE----
-CCDDCCCCDDCC-
----BABBAB----
-CCDDCCCCDDCC-
----EEEEEE----
-CCCDDCCDDCCC-

Spreading A, B and E out more would be better, but may make connections difficult.
