It maybe the wide angle view, as you surmised. The Dragon model's wing dihedral is more shallow than the actual bird which would put engines 2 and 3 lower than normal. My guess it is a bit of both the wide angle view and the model.
Here's two more mish-mash attempts. Sorry they are going in the same direction as the last two.
Currently, I have three B747-100s, five B747-400s and two 47-8s in the collection. I wasn't sure how many dash 200s and dash 300s were available but I was lucky enough to find two new-old stock models of those early Queen of the Skies variants in a clearance sale.
The dash 200 is a Transamerica Airlines convertible freighter to passenger variant N742TV produced by Gemini in 2001.
