"There is no such thing as a “design perspective.”"
Hello? There's a whole theory of design: grids, colors, hierarchy, typography, etc. It's not as simple as "drawing something pretty" as most may think.

(And of course some may pull this card as to push their personal preferences, as developers pull the "this can't be done" card often for the same reasons)
