The Duke is my favorite piston executive type. They look like they are going fast while just parked on the ramp. I have never seen one with wingtip extensions like the one in your photo, and I think that complicates picture taking a bit. But that's not what throws me off about the picture.
My preferred shot of the Duke would have been with a prime lens (50mm or so) and it would have included the nose of the aircraft. I think you have to be careful when obstructing the nose of most aircraft with another part of the airframe, as you have.
Some will argue this point, but in most successful aircraft photos, the nose of the aircraft has been treated with respect. What I mean is that the photographer has tried not to let the outline of the nose be compromised by background distractions such as light poles, harsh, contrasty buildings, groups of people or parts of other aircraft. In your case, you eliminated the nose of the aircraft entirely, and this frustrates the viewer right away.
It is also important on twin Beeches, though not necessarily the Duke, to include some engine detail. In this way, if you had the prop spinners in the shot, the viewer could quickly determine if it is piston or turboprop-powered-and Beech has produced many of both.
One last comment. Ideally could be a bit higher in the frame. It is noticeably closer to the bottom (horizontal) margin of the frame, with the result being a disproportionate amount of clear sky. It's hard for me to complain about the latter, as that is a commodity we have seen little of where I live!
Hope my comments help.
