So I have a few problems with the sheet. For starters he feels much more like a npc that should be summoned rather then a Player Character itself. A 35 giant Ice man who constantly freezes everything around him isn't gonna fit well with the Keep the Knights are staying out. Furthermore, his madness makes him a difficult candidate to be hired. Lancelot does enjoy internal conflict between his forces, and ofcourse doesn't mind the thought of one knight killing another; but the risk of one knight destroying nearly his entire organization is a different story altogether. 

There are grammar errors and typos here and there that make this sheet feel incomplete, such as "his madness and bloodlust can killed everything around him" 
There is also the matter that Ice elementals are the last elementals. What happened to the rest? Not to mention elementals are a more generic race and saying that only the Ice elementals remain is a bit restrictive on elementals a as a whole. I certainly expect elementals to be rare, but not extinct. Regardless I don't see much explanation to the elemental race, especially when you give notes that ice elemental are the last elementals. I don't mind if characters and races are vague in that sense but this comes across as lazy.

The risk that if he dies he will instantly explode into a nuclear ice zone that can "kill any being" is not only broken but just another nail in the coffin that Lancelot wouldn't bring a knight that was a walking bomb. 
Being able to raise an army of ice elementals is also a bit too much, the giant is already able to destroy cities and we have several characters with armies already. That particular ability just feels out of place.

Even if you were to fix the prior issues such as giving him a smaller form to transform into and being able to control his surrounding blizzard, I can't really see this concept fit in as it is. 

I won't stop you from resubmitting an Ice elemental character or work on a new sheet altogether, maybe you can make an ice elemental work in the Knights of Evil. But for now I am going to have to not accept this submission.
