I think that this one is an artwork I really want to improve because of the difficulties I had with Goku’s face; when I started the sketch the face’s angle was different and later I’ve noticed how that perspective was pretty difficult for me to get, then I decide to retreat because it seemed unfair to leave it in that status.
But I felt that the line art has slightly improved, it’s obviously a personal thought but the time spent in it is surely lesser.
Stay Imaginative.
