Saurav Raj Jain as Lord Krishna- Well, he is improving every day, n surely has his own style.
Drone- He's a very, very veteran actor,n hence simply great. I don't know y people don't talk about his acting much.
Pooja Sharma as Draupadi- She is actually quite good as a newcomer. she surprised me quite a few times with her powerful dialogue delivery n flawless expressions. Her eyes say it all, even she doesn't have a single dialogue.
Arpit Ranka- I love his voice n masculine screen presence.
Rohit Bharadhwaj as Yudisthir- I think, if we take only "acting" into consideration, keeping aside all stardom, then he is actually the best actor amongst the Pandavas.
Apart from this, I think Anoop n Riya Deepsi play their part well. Aham Sharma as Karna is certainly promising. N Arav Chaudhary is also quite good.
Another actress who, I think did well was Sayantani as Satyavati.
