Service Topology for Mid Size Farm

I am working on upgrade SP2007 to SP2010.  Below chart is a snapshot of  how I am planning to distribute the service across the various servers.  The goals are:

1. Properly distributed the load across the servers
2. Build a level of redundancy
3. Prove a scalable environment

I know I will need to make adjustments along the way.  This will at least give me a starting point.  Hope this will help you guys out as well.
