I usually use an A5 or A4 sketchbook for drawing. I would use A4 paper and HB pencil to draw sketches when I am at home. If I go out, I prefer to use an A5 sketchbook to write down or quickly draw my inspiration. The things that I draw the most is emoji, cat, and some creation that I am interested in game/video/Tv, etc. I want to use my sketchbook to practice my drawing skills or become the material library that can inspire me when my brain is blank. I want to play with the color and make some experiments with color use. Because that is my weakest part. Thus, I have to practice more. Sometimes I also like to draw on the tablet, on Photoshop, and Procreate you can use special brushes or create new brushes, you would feel fun on play with them or doing experiments.
