Couple of areas I see you can reduce weight
Rain cover. This weighs 1/4 of the weight of your pack and water can stiil leak in through pack straps. I use a trash compactor bad inside of my pack which weighs 40g.
Phone charger only bring if you have a place to chage obviously on short overnight you dont need it
Flip flops - do you need them? And for a light weight alternative you can take a blue foam pad, trace out the shape of your foot and a strap, then duck tape the strap. I think mine were under 2 oz for the pair. http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=46709
Water Capacity. You look like you have a lot. Do you need it all or could you leave 1 or 2 containers behind?
Other that that your the only thing that looks heavy is that you have almost 2 lbs of misc stuff. Looking through it it all looks usefull but it ends up being about 20% of your basweight.
