Beauty is only in the eye of the beholder.
Oh, I am not going to hunt for nits, loose nuts or failing rivets. The general impression is what counts in any adaptation of a prototype, and so far you have succeeded in capturing each and every unit's essence.
But yes, you are right, this unit will probably go down as one of the less than beautiful ones in the NS Heritage Fleet.

Some units will be liked and photographed more than others and the favourite ones will stand out.
