The dock of the bridge... Er... The frame... Oh screw it, I'm tired.
Well the flat top part of the dock seems a bit flat, as if we're seeing it from an overhead angle. However, the angle of the planks suggests otherwise. Then the angles on the handlebars (I said I'm tired!) seems very confusing. Top of the bars seems at an overhead angle but the way the vertical pegs join onto the bars is flat, like you're viewing it from a head-on point of view.
...Really, I swear I'm tired!
