Figure from imagination (mostly)

Hello! I don't think your line confidence is lacking as much as you probably think. You have some nice variation in line weights; the interior lines are finer, while overlapping forms are stronger. It's all good stuff. Of course, we can all improve, but you’re definitely on the right track. As for the perspective, you’re also doing well here. My feedback is just meant to illustrate a trick I like to use when I lose track of my perspective in a drawing, which seems similar to what happened here. Everything is working well, but something just feels slightly off, right? So, how do we find our perspective again? Z-Axis (Center of Gravity): We need to identify the figure's center of gravity. I find the hip box is usually a good place to start. Find the center of the hip box and draw a vertical line straight down in perspective. In your case i was feeling a 3 point convergence for the vertical line. We want to see where this line falls in relation to the feet. In a standing, static pose, this line should usually fall between the feet. It will often be close to the center, but in a pose like yours—where the figure is leaning on one leg—it will fall closer to that supporting foot. If this line doesn’t fall between the feet, you’ll usually see where the problem is right away. X/Y Axes: (The Angle of the Foot) You can usually determine the perspective of the X and Y axes based on the angle of the foot in a pose like this. Draw a plane around the bottom of the foot and use it to project the X and Y axes of your perspective box. Once your perspective is established, it’s just a matter of making adjustments. In your drawing, all I had to move was the forward leg so that the knees were aligned along the grid. You may want to redraw that leg to fit your taste, but at least now you can see where it falls in space. Keep up the good work!

The shapes I'm providing are lacking, but IMO it's best for you to take it gradually, I saw on your other post you're just getting back to drawing. Drawing is very labor-intensive, it takes a lot of cognitive energy, so the fact that you decided to go back to it after a break is awesome, especially if you're often not pleased with your work (because you put work and time into something that may not give you the dopamine of liking the end result). When I myself went back to drawing after a long break, doing a ton of exercises with just purely shapes (cubes, cylinders, etc, I'll refer you to Practice Drawing This again) and line drawing exercises (ditto). It may feel silly doing it at first, and I didn't notice the benefits of drawing a bajilion cubes right away, but eventually it just hit me that I am using the same techniques and strategies when drawing actual people and objects as I did when I drew that cube. AN IMPORTANT NOTE, I would actually suggest you practice Stretched and Squeezed shapes specifically (Practice Drawing This has a special section for that) because from what I observed, you tend to break down your anatomy into these. On the website, it's 3D models --> Stretched And Squeezed Forms > Stretched / Squeezed box. You can rotate the box and use the dominos icon to make it change shape (from stretched to squeezed).
