Looks great.
A little funfact regardeing the DC series. The wing up to the outer wing section containig the ailerons had 3 spars, as opposed to the normal practice of using two spars. From a fatigue design point of view, that is very efficient, it is a major reason why Douglas aircraft had a much longer technical life than most other 1950's airliners. Just a side remark. By now, the low availibity of Avgas, the fuel for the PW engines, has put most of them in museums.
