Here are 2 of them. It is a combination of observational drawing and imaginative drawing. (NOTE: They are more like practice drawing than proper drawing.)
When I first read about perspective drawing lesson, all the "sighting" and "measuring proportion" seems very complicated and hard to understand. But after a few hours of drawing a simplified version of a small corner of my kitchen, I was amazed of how real (perspective wise) it looked on paper.
Perspective drawing is still a newly acquired skill which I need tonnes of practices. But I found the process of using lines to create 3D objects / landscape on paper immensely interesting. It is almost "magical"!
You might also notice from my 2 drawings that my inclination to all things weird & strange keep cropping up everywhere. When I finished the little box drawing and the office corner drawing, I had this dialogue in my head.
Me: O.K. that's good! You did well in your practice, but ... something's missing?
me: What's missing?
Me: "Stuff" ... "Your Stuff" ...
me: What do you mean by "My Stuff"?
Me: I mean ... yes, this is your drawing but it is NOT your drawing!
I looked at the drawings again and the little spotted creature started to take form and crept into frame.
Me: Ah, there you go, you dumbo! Now that's more like it!
I think I was so caught up in learning the drawing skills (based on observation, hence realistic drawing) that I actually took the term "observation" to the letter. I drew what I saw and forgot to continue to let my imagination fuel my creativity.
Through the little spotted creature, I reclaimed MY drawings!
(BTW, I'm still wondering what kind of creature it is ... any idea?)
