Bandwidth on Vlan Interface for Sharing and Dedicated

I have some problem to set some bandwidth using Vlan interface.
Each user have different subnet and vlan-id. I`m confuse to create bw sharing using 1 parent (256Kbps) and have 4 child on each client with have vlan-id and subnet.

[ mikrotik ]
Internet--------(wan)--------(lan) ->vlan-1 (/30)
->vlan-2 (/30)
->vlan-3 (/30)
->vlan-4 (/30)

->vlan-10 (/29)
->vlan-11 (/29)
->vlan-12 (/29)

vlan-1,2,3,4 for bandwidth 128Kbps (sharing)
vlan-10,11,12 for bandwidth dedicated 256Kbps.
Please help me, to configure my queue using queue tree.


Thanks
