The last sketches where only done with my ball pens and a strict time limit of 10 minutes. After some sketches it felt relatively “easy” to estimate the remaining time while sketching and I will try to stay in this time frame for my oncoming sketches. Reviewing my last sketches led me to the conclusion that I should work more on hatching / shading. Also elliptical shapes are very hard to get right,…but deconstructing them into smaller pieces helped me a bit.
For the next sketches I will switch from ball pens to Paper on iPad and use all the given tools of the app. So long, happy sketching!
