Welcome to Steemit @sajeelahmad, you will find you are among many friends here. This is a great community, even for introverts. :) Spend some time reading the posts and comments of others, get to know them. There are many talented Steemians to show you the way.
Add value to your picture posts with a little commentary and just be you. I look forward to your posts. I have a few helpful tips I've learned along the way from others and you can scroll down my blog to find them.
There is also a steemit.chat that is full of people standing by to answer questions and share some information. Steem On.
Let peace be the journey!
