Now that I really looked at your pics, yup, really need to readjust your cable yoke lower and closer to your brakes. But I also agree with Shimagnolo that with such a long cable travel because of your long steerer tube, you may still not get enough braking power and too much shudder. Moving the brake cable hanger thingy to the fork crown should solve that. Never seen this before though.
