Twitter Bootstrap is a double sided sword. I say this because unless you fully customize it your self and make it a point to make it stand out..it is easily recognizable as a bootstrap "template". Your site is literally a slightly edited copy of the "Carousel Jumbotron" example that they show on the bootstrap site : Carousel Jumbotron
For this reason, I just try to use less/none of the components of bootstrap and basically only use the grid system.
