First of all, I was really charmed by the things you shared in this class :). I played with vectors before, but I always found the result to be a little lifeless, because the lack of texture. I am not an illustrator, but now I feel I wanna explore more. So, thank you for this!
After brainstorming the theme, I made a list with lots of witchy items, I gathered some references and then made four sketches (I know it's not ok to rush this part, but I was really anxious to start).
I drew the witchy equipment in Photoshop, following sketch no. 4, but I wasn't very happy with the composition, so I played a bit more with the flat shapes.
And then I moved on to the inky part :D. I used a flat brush, a dip pen and a Pilot Parallel pen.
