Hey, @Canyon Braff! It’s been a while since you posted this, and I’m curious to know if this “lack of progress” perception changed in the last couple of months or if the feeling has stayed roughly the same. If it helps at all, whenever I feel stuck regarding my art, I like to remind myself that my own perception is subjective and biased, and just because I’m not feeling so great about what I’m making at that moment, it doesn’t necessarily mean that I’m not evolving in some way. It can also help to remind ourselves that growing in art is not a straight, steady line, but a wavy roller coaster with alternating periods of growth boost and stagnation. I’m attaching a couple of images that sum up this idea, maybe you’ve even seen them before. One more thing that has helped me unstuck in the past is to vary up the focus. In your case, since you’ve been staying consistent with figure drawing for such a long time, perhaps you might like to dedicate a few weeks to studying something else entirely, such as lighting, or storyboarding, or perspective. This change in focus could help clear the mind and freshen things up a bit. Above all, I’d encourage you to try to be kind to yourself as much as possible. Sometimes, it’s almost automatic for us to create a lot of expectations (“achieve this”, “optimize that” etc.), then self-pressure and anxiety can arise at the smallest sign of falling short to those expectations. Making art is a lifetime experience. Try to enjoy the process in each drawing, embrace your own journey as it is, in your own time, and know that simply keeping a consistent pace over the long run (a.k.a. not giving up) is the most important (and often most challenging) achievement. Hope this helps! 

Mate, I feel exactly the same and I've been learning for a few years. Glad I'm not the only one. Maybe, and I'm sure you've heard this before, we need to just enjoy the journey. What are you learning for? Because you have to or because you enjoy it? If you approach it with a frame of mind of 'play' and looseness and joy as opposed to rigid drill style practice ironically you're art would come out of you easier and be more beautiful. That said, I TOTALLY get how you feel and I also struggle to take the above advice. If you watch artists like Rembert Montale or Ian Mccaig sketch you'll note how they seem to do so joyfully and with a 'no pressure' attitude. Maybe we should do the same

Hey, I'm in a similar boat where extreme diligence and countless hours practicing drawing daily is showing little to no return. I'm currently taking a step back and drawing as a habit, rather than "because I should," and trying to learn more from observation. Watching another artist draw (traditionally, digital is much less helpful) with the video on mute, or reading an art book for a few days before picking up a pencil again, can help a lot. I've seen people get better quickly despite not drawing for months at a time simply because they were digesting information and knowledge during that time. Give it a try, I am too. Godspeed and good luck.
