Hi @spgeeth, I see that you just joined Steemit and you have beautiful pencil works. Up here there are many people who do draw and paint themselves but also many who just present someone else's that is why for curation community and trials it is important to know if those works are yours or not before giving you upvote. There are few tips how to attract those curations:
First when you do your work just do couple of process pictures to capture the steps, if it is an old work and you have only the final result then please write more about what and why you have done. If you are using references many curation communities would like to see the references links. If you have your website or instagram where you have already posted the same works better to mention because if someone will see the works somewhere in other websites it might be considered that they are not yours.

Also there is @Ntopaz site that supporting talented Artists, here is hte link to the posting guidelines and you need to post using their App but they automatically appear in Steemit too.

I am attaching the recent post with the explanation how to post:
