I am 35 years old and I majored in computer engineering and had my master's degree in project management. After a hand injury two years ago, I decided to have some major changes in my life. Now, it has been almost a year since I seriously started to focus on studying painting on my own. After deciding to focus on painting, I started to grasp the vastness of knowledge that I must learn such as, how to use brushes, mix colors, prepare canvases, draw perspective, build layers, etc. Of course, since childhood I did some watercolor paintings, but it was only 1 or 2 paintings in a year. That is why it's a huge struggle for me to understand oil painting. As a beginner, please bear with me.
