Hi Jose and welcome to the poll board. :)
My vote would go to Jake Gyllenhaal in 'Nightcrawler,' one of the best performances I've seen. That he wasn't nominated for an Oscar goes down, in many books, as one of the Academy's curious snubs. I also think Gosling's performance in 'Blue Valentine' was exquisite and deserved more attention. In general, your list is off to a strong start.
This is a good idea but I'd suggest revising some of the text under the options to make it briefer and more concise. Generally, voters seem not to like to read a lot, sometimes quite unfortunately, I think, but polls with less text tend to do better. I like that you include some of the award information and keeping that definitely seems to make sense.
Here's some information that you might find helpful:

And nice pick, Jake was outstanding.
