Good job, Kiran
, almost correct
I know we haven't talked about people yet, so I won't ask about them, but I tried them out anyway
Well, as a matter of fact your question is not about people, it is about perspective alright.
The three sitting people further away are not in correct relation - perspective wise - with the nearest sitting person.
BTW, the left standing person is too tall. Assuming that the observer stands at ground level and that all people are about the same height, all figures standing on the ground level will have their "eye level" at the eye level of the drawing, aka the horizon line .
(There is recent discussion thread on the issue here
Keep up the good work
