Sorry, but it's NOT of "acceptable quality" regarding the resemblance to original.
Going from tail towards nose:
-ex-gun turret has been reworked much more,
-radar antenna (?) dome instead of lower gun turret,
-apparent lack of wire antenna,
-different set of antennae on top and below fuselage,
-different underwing hardpoints,
-completely, not just "widened" engine intakes (and likely exhausts too, though I haven't checked it),
-lack of upper front gun turret,
-
totally redesigned cockpit and nose.
