I suppose you wouldn't mind if I created a build based off this would you

I definitely wouldn't mind, please feel free. I don't have any ownership over my builds; they're all only possible because of Bethesda and I've only used their own assets, so far be it from me to stop anyone from taking influence from my work.

You'll notice it has more than a few similarities. Kinda like the Black Ranger is to The Wraith Ranger

Similarities are fine, just avoid outright plagiarism. 

What I mean is the normal battle style will be the same (dodges, blocks, bashes, angles, ect) just with a few extra touches like cloak spells and such.

Quick question: what do you mean by angles and how exactly should I fight (for instance my current character blocks an opponents attacks and bashes a lot to stagger enemies, rush up behind them and does a power attack to stagger them again and start quick attacking) is there anything I should change to my fighting style.

Yeah, that's pretty much the right of it. If you're facing two enemies, try to separate them, or place one of them between yourself and the other, so you turn it into two separate 1v2s rather than a 1v2. Though skyrim lacks actual parrying and dodging mechanics, you can simulate them to a degree with blocks and jukes. Try to be aware of your surroundings and use them to your advantage. Just generally play with a more tactical mind than you might normally (if you normally play anything like I do, that is -- hack and slash style).

That's pretty much the same thing I did with the Nemesis as well.

I personally prefer to go to Ansilvund and get the Ghostblade as like an Ansei "Trial" for when I decide to play an Ansei/Sword-Singer
