I do pencil sketches especially portraits in my free time. I have published some of my recent sketches in http://pencilsketch.blogspot.com.
If you like it and want me to draw your own portrait you can send your photograph to me. Though i am doing it in my free time i am not doing it for free :) Here is a deal. If you think i have done a good work in your portrait, you can decide your contributions by yourself and send it to me or directly to any charity and let me know where you donated what.
I usually donate to the one mentioned below. It picks up mentally challenged people right off the street and provide medical and vocational training to integrate them into society.
You can find more information from this site.
