Actually, Shivya has improved greatly as an actor.
And the fact that she acts like a real, relatable human being, rather than a glamorized being as I've seen many times before is a great asset to her. She can use her rawness to an advantage. Further, her range in appearances will go a long way too. She looks as radiant donning a simple avtar as she does a slightly glamorous one (as seen in her gorgeous suits and now that gorgeous sari). I'm sure she'll go far...
She also has a strong fan base now, as well. Such negativity with no justification with facts isn't appreciated on this forum... Wishing Harshad and Shivya all the best.
