My only suggestion:
Since you're implying that delete has an "alert" connotation with red, following the call to action with green disarms me. I don't feel as though I need to be worried about the implications of the action.
However, I do like that we're asking the user to confirm their decision. So if we're to follow that thought, this is what I would consider a logical step since we're still alerted to performable action.
If this is a poor idea, let me know and I'll crawl back into my design hole. ;)
