Enriching my hobbies

Inspired by one of the blogs that I found on the web, I thought I'll upload a couple of my sketches. The first one is actually drawn from a photo. It matches 80% to the photo. :-) There's a lot of learning while sketching this. There's another picture which I drew, inspired by R K Laxman's cartoons. I am not sure if it will have any copyright issues. Please let me know if it does, so I can remove it.
