Yeah this is a bit embarrassing. I was cleaning through one of my older folders and I found this old sketching exercise that I did back in 2009 (Image 1)
- 15 min
- not allowed to use erasing
- no references allowed
- Opacity on brush allowed
I think with the first one I used a 50% opacity on my round brush. So to compare to how I am now, I redid the exercise to compare. (Below: Image 2)
I also used a 50% opacity and tried to keep it as close as I can with each other. I didn't use up all 15mins and did some tweaking to the angle and kept to a lighter shade. Still lots of room for more improvements!
I think revisiting old sketches are always fun and you can really feel the difference not only with technique but also the familiarity you have with your working tools. =)
