I think your window would look better if the blinds didn't contrast with the wood trim. You could replace the blinds with ones that match your wood trim. But, I think a warmer and better look would be solar roller shades. They are available in many different colors and some of the materials have a warm, earthy look. I would also add stationary draperies on each end. The first picture is to give you an idea for a bay window. The other 2 pictures are
to show few more shades.

(At first I thought of roman shades or woven wood shades. But these types of products stick out several inches as they stack up. Since your windows are close together and they are at an angle to each other, these types of shades would probably hit each other as they lift up.)
