The points which come to mind about Poonam are:
-Powerful voice suited for classical singing
-Her sanskrit education which helps in diction & clear pronunciation of any language
-Ability to sing classical/semi-classical songs effortlessly, versatility
-Dedication & hard work to learn music and the stress she lays on the finer aspects and the minute details of a song, its sur, taal, laya, bhava etc etc
Looking at the Hindi film music scenario which nowadays is filled with disco/pop/item numbers of short lived fame with singers already earmarked for such kind of rubbish songs which have no musical value in them, Poonam would do well in avoiding, jumping into the bandwagon of big bad world of Bollywood.
I would recommend Poonam to undergo tutelage for classical music from the likes of Pandit Jasraj or Kishori ji and make a mark in the field of Hindustani sangeet post SRGMP.
Once in a while she could render some classical/semi-classical songs in films also, like the ones made by Shyam benegal, Sanjay leela bhansali, vishal bhardwaj etc, but pure classical music should be her priority, so that India could have another pure mesmerising sangeet vidushi in the tradition of the great Gangubai hangal or Girija devi.
