What an amazingly detailed illustration. I really appreciate that you showed us close ups of each section of the picture, because otherwise I would miss almost 90% of this beauty.
Is there any significance about the middle aircon? Its bottom part is painted orange, unlike the other two.
Thank you @scrawly ! :) I worked hard on many details. Oh, you have good eyes! :) No, it's just a fault. :) I forgot to color it to black.
