Yeah it looks good.  I definitely wouldn't tie the two drain lines together  before they enter the sump as previously mentioned.  I would have separate drains straight to the sump.  I also prefer at least two drains per tank for backup so I would want another one on your main tank, but if everything is dry walled you might have to live with what you have.
