Hello there.
This image looks familiar to me, I know I have seen this character before but I cannot recollect from where. This is why I chose the character, with his expression and the finger too. He ask nonchalant and he doesn't care about the opinion of others.
I changed the white color to off-white, and the eye lid and finger nails. Those are the major changes I made in the drawing.
I later found out that the character is Grouchy smurf from the Smurfs movie.
Below are the steps to the drawing:
Thanks.
