So basically, I am planning to include 10 pieces in total in my section of the exhibitin (it's a school organized exhibition), and only 5 of the pieces are completed (albeit with a little room for improvement, as always). I am not necessarily behind on schedule, but I had to scrap two whole completed pieces because they were some of my weak pieces and they would just bring down my grade. Additionally, with upcoming final exams, I am struggling with balancing my time for revision and for painting while I still have acces to natural lighting from outside. My goal is to complete those 5 paintings while having extra room to make one other painting just in case if i'm going to be told that a piece is not good enough.
Any advice regarding painting techniques with acrylics (specifically how to keep my mixing palette wet for longer periods of time), or digitlal painting tools on krita would be much appreciated. Thank you for taking yor time to read this :)
