A bastard of Su-27-esque planebase, a glance of F-22A Raptor and a semblance of YF-23 Black Widow.
For my taste (on looks): "Little Russian taste, tons of mixed values. An identity crisis."
For me, "Russian taste" must be something beautifully balanced, like MiG-29s and Su-27s. But this PAK-FA really looks like my imagination of an "uber fighter jet" when playing pseudo-realistic air combat video games.
