Typically, you will want your leg angle at 6:00 to be around 30 degrees (or 150 if you're measuring from the other direction, so you may consider lowering the saddle more. I'd also consider moving your stem up, with the spacers all the way on the bottom except for the top cap. As you lose weight and gain more core strength and flexibility, you will be able to lower it, but that will take months. Also, the saddle being too high can be a cause of "saddle pain" too.
