As the title says, this is Connor Kenway's bow from Assassin's Creed 3. Yes, it's a little different from the game, I had to change a few things in the design so that it would actually work as a bow, like making the handle a little thicker to keep it from bending from all the pressure and thinning out the limbs a little so it would bend easier. I'm not sure about the colors though, I used several reference pictures (as well as the game), and they all seemed to be different shades. I finally settled on the medium-ish brown and I think I made the right decision.
Yes it is made from PVC, and yes it does work. I think I actually made it a little too strong, it broke one of my arrows and split the knock all the way down the arrow. I also used a similar design and made a Hunger Games-like bow (that one works really well, and doesn't break arrows).
Here is the bow:
