A good exercise for this is to place two dots on the page then with your pen not touching the page, go through the motion of drawing a line connecting the points. Do that motion a few times then commit & draw the line. Go over it a few times trying to be consistent. focus on starting & stopping right on the points. Try to do it with only the pen touching the paper & focus on the feeling of your arm & shoulder doing the work. After, check your work with a ruler & a red pen to see how you did. Another exercise is to use a ruler to draw some long lines then go over them free hand & try to match them.

You are doing an excellent job schmal! I do notice you make the shoulders a bit wide. But other than that I don’t notice much issues, keep it up!

These look excellent. When it comes to connecting your lines, the way you have done it is fine for this assignment. Try keeping your lines a bit lighter as you lay them in and then slowing down to add a darker line in the areas where your lines connect. I personally think your lines have really nice energy. For this type of drawing you won’t get perfect proportions so don’t stress about it too much. These are very successful, nice work!

I like your line quality.

I think you are on the right track. You're doing a great job implementing CSI lines and you have a good understanding of gesture. At the risk of sounding cliche, keep practicing this skill. You seem to be at the stage where getting the mileage is going to benefit you the most. I think it's a good idea to keep a small sketchbook at all times and draw shapes from life if you can. Practice drawing dynamic shapes from imagination as well. You can draw seals or anything else that you find enjoyable to draw. Keep up the good work 👍
