I don't think she should stray from anything...I say spread your wings!
I like the fact that Noon tries different roles that's what make her such a talented actress. The fact that she can portray a variety of roles...you see there are some actress who can act great in drama but they don't spread their wings...they don't try out "new things". Can I say they are always portraying the nice n'ek in almost all their lakorns. Although it doesn't make them a bad actress it just make them less of a well rounded actress.
Benz played a Mistress in that lakorn with Ann Siriam...which was like wow!
I think Noon is among those who have tried many roles...others would be Benz, Kob, Aum, Joy, Anne, Mew, just to name a few.
