Through years of work, I have realized that most people cannot visually understand a drawing, even if it is a photorealistic render. Something in those shadows is unclear to many. I've even seen some architects who don't have a very clear view of the perspective drawings. But every hand-made drawing delighted everyone. I even think they are more thrilled that they find it very difficult to do than they understand the drawing better. These are very good illustrations. Enjoy your work.
That is such a thoughtful comment, Thank you a lot for appreciating and shedding some light on reality.
Hope you have a great weekend:)
