Cinnamon Swirl Raisin Walnut Whole Wheat Sourdough Bread

I changed a recipe I found for Cinnamon Swirl Sourdough Bread to include whole wheat, two kinds of raisins, oat bran and walnuts. It came out OK, but I think I may have left the dough to prove a bit too long as it had very strong sourdough taste.  My husband liked it, however, so that's a plus!
