First two drawings
Alright, these are my first two actual attempts at drawing since I started trying to learn how to draw. The first one was done in Apple Notes, and the second one was done in a dedicated drawing app called Sketchbook.
I feel like I leaned too hard on the tools and aids in the second one which made it feel kind of lifeless.
Not to mention I accidentally gave Shadow a fivehead. Lol
I know nothing about shading, what are some things I could do for practice?
Where should I go from here to develop my skills. I already feel stuck. Lol
Comments, criticisms, tips?
