It does have twin tails and engines, but that is as far as the similarity goes (differences include single vs twin seater, presence of canards, swing wings on the F-14 vs tri-plane on the SU-33/J-15, folding wing tips on the SU-33/J-15, etc). Look at the pictures below. From them it can be seen that the J-15 is simply a SU-33 direct copy, while the F-14 is significantly different from either.
