Feedback on Strength Faith/Int/Pyro Build?

This build. It is the epitome of my boredom. I've never really used a strength weapon before so I just thought I'd go with the legendary Zweihander. And since I, personally, haven't seen a trio magic build used in PvP, I figured I'd try that out too. Is it gonna be viable? Probably not...but anywho tell me what you think.

That looks like the one I fought in new londo ruins?

Honestly, I doubt it's gonna be very successful. If you manage to beat good pvpers with that on a regular basis, you can call yourself a master of Dark Souls. I think it's a cool idea to unite all three magic types in one character, it can be very effective actually, but using a zweihander on top of that is a little bit too much while staying in the pvp level range.
Anywho, I fumbled with mugen a bit and this http://mmdks.com/32r2 turned out. Tried to keep your idea, but gave you 55 poise and changed the catalyst as well as talisman for higher magic adjust. Also changed the spells a little, dark bead/dark orb combo can trick people the first time you pull it off while dealing decent damage with the TCC. Black flame I find more useful than GC with the poise break, HCSM, WOG and fire tempest are fine. Worked at your Str/Dex, you can still one hand the zwei but for maximum effectiveness, two hand it when you swing.
Yet again, really challenging build to play, especially selecting the right spell mid-fight. I know already I would constantly fail at this part and make my char look like a fool trying to cast let's say fire tempest with the talisman .
Good luck!
