Halfway through, when I noticed that I'd gotten the dimensions wrong, all I wanted to do was cancel and start again till I make a perfect sample. But then I remembered what Jorge said in one of the first lessons about how what you learnt while drawing is more important than the drawing itself and so I tried correcting what I could (which I shouldn't have) hence the very thick lines and spots at certain areas.
I share this @jorgevandeperre because I know I'm far behind and wouldn't want to stress you in making different posts for every of the home-work I'll be submitted throughout the week....I'm earnestly looking forward to your critique..
The process....
Thanks for giving me the opportunity to grow.
