Ok, so you know to upgrade your resists, all good.
I reckon you should keep an eye open for a new windforce bow. Either look for one with (more dps naturally) and higher crit damage or a socket so you can insert a emerald into or even a ruby if you prefer. the dps on yours is good, but 64% cd is a little low and holding you back on crit damage.
Also your nat's cloak isn't doing much for you. You nopt using the grenades skill and extra life on globes/potions is meh. Look for a nats cloak better suited to your characters skills or get some vitality or more dexterity on those variable slots.
