New Hyper-V Environment - system assessment

I have developed a new domain with Windows Server 2012 R2 and Windows Essentials in a Hyper-V environment and would like a system assessment performed to make sure there are no glaring mistakes with the architecture.  This is for a small corporate office with 10 users.  Hardware platform is Dell PowerEdge 710 server with 48GB of memory and six 500MB drives.  There are two virtual machines on Hyper-V core server, first VM is PDC, Active Directory, Anywhere Access, Windows Essentials, DNS. Second VM runs Exchange 2013, Symantec Mail Security for Exchange, WSUS and print server.
