@waffles well yo udon't have an amulet or glove equipped so i would start there, lol.
First i would work out some Life on Hit, or Life steal for your character, as your completely lacking. After you get that hashed out, work on increasing your crit chance.
@morganism Nice stuff ^^ i would shoot for a weapon with life steal, and perhaps change out the pants for inna's, or get a crit lacuni for the movement speed.
Next upgrade should definitely be those pants! With a skorn build you aren't benefiting from the IAS, there is no AR, and you are sacrificing your main stats. I would consider picking up some Depth Diggers and gain a few thousand life and most likely damage from the increased int. Besides that, looking pretty solid! :]
