Well, here I am! I chose the exaggeration exercise for my final project, and I'm so happy with the result! I did it with Adobe Illustrator because I found photoshop workflow a bit confusing, and I wanted to stay motivated with the course. I didn't found any problem! All the directions and tips go beyond the program you use, if you master the pen tool hahahah. The final brush textures obviously seem a bit cold being only vectors, I'll keep trying next time!
(I couldn't scan the rest of the exercices, so this is the last scan and the final illustration)
Tom, thank you for your work!! You're such a great teacher.
