Looks great. I'd get the green one. I'm commuting on a similar bike. You really can't go wrong with bikes in that price range from a reputable brand and dealer.

Without riding it, the great unknowns are going to be fit and comfort. Can you test-ride something with similar dimensions?

Depending on terrain and how much stuff you plan on carrying, consider the possibility of a rack, basket or panniers, and fenders, as potential add-ons.
