The only issue I see from your photos is that engine movement/vibration haven't been taken into account. While having the piping brought that close to the waterpump is convenient, you still need to ensure plenty of movement is allowed for vibration and torque movements. From what I can see in the photos you've taken, the best spot for one of the rubber (and thus flexible) hoses is probably coming out of the radiator down under the oil-pan. This will place the movements along a relatively long section of flexible hosing.

If you were going to run flexible sections on the runners out to the back of the car, you'll be asking the rubber hoses to flex in a torsional movement, which will cause them to fail in relatively short order.

I can't see the other side well enough to make any recommendations there.

Hope that helps.
