I wouldn't say that. The wings could fold back along the fuselage for storage, kind of like Hellcats/Wildcats of the US Navy back in the day.

Ascetically speaking, I feel like it fits perfectly! The artist purposely made it for a Dieselpunk esq world, which is what we seem to be set in. Not to mention that this world actually somewhat ahead in aviation in comparison to our world in a similar time, so I don't see why it can't fit in. It's a special heli for an exploration! Not to mention tilt rotor designs like this have been around in our real world ever since the late 40s! No joke! See aircraft like the Focke-Achgelis Fa 269, or the Transcendental Model 1-G. Of course these never really made it past prototypes, but we're in a world wholly dependent on aviation! 

Don't let dreams be dreams! Let this bird fly!
