At a glance it might help you to replace the life pillars with life pendulums, those with the 2 rustlers should give you enough green to power the queens.
And 18 land seems a bit much, try cutting the air mana down for dragon fly's? or more pegasi. Just my 2cents
Another option would be to replace the life with 3 light pendulums and 2 light pillars and change your mark to life.
