There are rods that connect to create slopes. If you've already dressed the other windows, this one should be similar, if possible. You've gone to the ceiling, so it wouldn't look right to start at a different height on this window. Look for rodding systems that slope and you'll be able to finish this in a similar fashion. Much luck.

Thanks! I'm gonna look for those sloped rods (or make one myself ;).. the other rods are just electrical conduit)
