It took me a couple of months to get to 100 and getting closer to the end I decided to put in some references from Pinterest I thought working better for me. Yes ! it's far beyond the 10 days challenge it was supposed to last, but I couldn't have made better than this. Gradually I slowed down and conceded myself more time to study details and cross hatching. Many thanks to Ahmed Aldoori, it's been so inspiring and productive.
