1250/1850 Escalation Tournament HELP!

I have a 2 day escalation tournament coming up, and could use some input on the list I've put together. I have to use everything I use in day one, on day 2. No changes are allowed, only additions to the army. I can add or beef up units, but not take way or move anything. First day the limit is 1250, the second day is 1850. So anyway, here are my thoughts...
