Nice build, my one problem with it is that you seem to be trying to use the wrong tools for the wrong job. For example, you have both Improved Sinister Strike and Hemorrhage. Which one will you be using? The damage buff from Hemorrhage isn't worth it alone, and for the points you could take Ghostly Strike to intersperse with your Hemorrhage/Sinister Striking, or maybe Remorseless Strikes for grinding.
I still think Hemorrhage, a mainly CP generating move on the cheap, and Improved Sinister Strike are not two talents meant to be used together. The two points in Imp. Sinister Strike could be used for better things, like 2/2 Elusiveness (here) for quick getaways, or maxing out Lethality (here) for better crits.
EDIT: a new Rouge, you say? Be careful, many complain we're overpowdered.
