After having read your opinions I would like to add something which might not be visible that well on the posted “before” and “afterwards” photos because the pictures are only showing parts of the relative golf hole.
I still remember what the course looked like before Krause's renovation, therefore and also out of fairness I have to say that the course with the renovated bunkers looks much neater and tidier than before... That probably also was the impression Emil Weber’s parents had playing the course recently after renovation...this might not come through the photos...
In this context but also with respect to the positioning of the new bunkers my (amateur) opinion is that David Krause did a good job renovating the bunkers the way he did and hence improving the general appearance of Hamburg-Falkenstein golf course very much.
When it comes to the look of the bunkers that seems to be very much a question of taste also, as one can see from your remarks and as Sean Arnold's post is suggesting. Personally I also find these noses too big...
I know that David Krause studied aerial photos taken in the 1930s and that he thoroughly looked what the course looked like then. I don’t think it was his approach to recreate (=restore) the look of the bunkers exactly the same way they appeared in the 1930’s.
As a golf historian I would obviously love to see the bunkers almost exactly look like the originals from the 1930’s, but I fear this was not David Krause’s approach nor the assignment given to him by the Hamburg Golf Club Green committee officials..
Having said that I would like to show you some bunkers I saw while playing at Chantilly lately…I know that Chantilly is not a Colt Course, but it is an inland course of a similar standing than Hamburg Falkenstein. On some of the old holes of Chantilly’s Vineuil course there are still some bunkers with rough edges to be found which I very much liked looking at:
