That penguin drawing has a lot of style. I like how you used loose searching lines for the vr girl whilst still maintaining a smooth line quality. My only criticism is that I think you should have used lighter searching lines on the hand. What you could have done instead is lightly sketch the direction of where the lines should be pointed to, then going over it with a darker and smoother line.

the its kind of wonky but I can really feel the perspective on this one

I can definitely see the improvement, nice job!

awesome love the shading

looks nice can tell the hard work paid off

how I add texture to my drawings while doing digital is that I color in by hand and use hatching or cross hatching instead of using the fill tool

There are a couple of things that I can give a critique about: - Please fill in the shapes more fully, because if you don't, you aren't really shading the form itself. Maybe test out different brushes, this looks like it's a pen brush, a pencil brush is more appropriate. Pretty much all drawing apps have this. If you want some free options, I cannot recommend Krita enough, it's a really good program! - Try to select more evenly spaced values for this exercise. The difference between the darkest dark and the dark grey isn't really that much, so the difference between the two isn't really visible. The fact that you're using lines instead of filling the forms also makes it different to notice differences in shading. I've attached my attempt to see the difference it makes to have evenly spaced values; Also, are you using a mouse for this, or are you using a drawing tablet? If you're using a mouse, I think it's best to either invest in a small drawing tablet, like a Wacom Intuos S (or something similar), or do this course using traditional media. Like Stan said, print paper is really quite cheap! Hope you keep at it, and good luck for the rest of the course!
