The biggest problem with your build is that you don't hit the 99% fcr bp. Also, you have absolutely no need for poison creeper.

Here are my suggestions: either swap out the maras for an amulet with 19-20% fcr (geddon fletch if your on east works fine) or use two 10% fcr rings (with good secondary mods). Also, you should use ber'd ss and have a sanctuary in stash.

As far as skill distribution you went for life instead of massive damage and except for the poison creeper there is nothing wrong with your skill points.
Hope this helps.
