You also seemed to have missed 2 Brain Freeze procs. You had 25 procs, but only used 23 FFB.
You also only used Icy Veins once. With your kill time of 4:36 you should be able to use it twice. Use it at the start, then again when its up. If possible, delay it a few seconds so you can use it with Frozen Orb + Prismatic Crystal combo.
Those are just a few quick things I noticed.
