The tip I can give is for you to take a break from drawing for a week, but another tip that might make drawing more interesting and for you to study different things, and vary it, for example, on one day you study a little about animals, on the another about landscapes and so on, because repeating the same task makes the study very boring and mechanical, besides it is important when you are studying, to focus on understanding the subject, not on making the study look beautiful, since as much The better you understand the subject, the greater your quality will be when applying it to your drawings. Furthermore, I recommend you take some time, even if it's just 10 minutes, to draw whatever comes to mind, without or with some references, focusing on having fun drawing just because you want to draw something, over time, this will help you draw without so much reference, although they are important, but this will allow you to draw what you want, being a really cool way to do it. fun, and taking away some of the burden of having to make beautiful and super well-made drawings, so my recommendation is to try to make the task more fun, and remember that it is important to ask questions about how you can improve and have to correct what you ended up making mistakes, thinking that your mistakes show where you can improve.

I hope this helps you in some way, a hug.
