Is it right this?
I want to ask somebody if I can draw him. I was thinking about tell him:

"I would like to know if you don't minds if I do a skecht of you. May I do a draw of you?"

Is it right? Or are better ways to ask?

Answer

I agree with the above comment.

Would you mind if I did a sketch of you?
May I do a drawing of you? (Drawing is the noun of verb draw).

:)

Answer

I would phrase your sentences like this:

"I would like to know, would you mind if I did a sketch of you?"
"Is it all right if I do a drawing of you?"
