Progress

I needed help knowing when I’m ready to move on on practicing art. I’m just a beginner and I’ve been struggling on if I should move onto the next step of a human body part but I’m just not sure if I’m done practicing or if it looks good enough that’s acceptable to the brain to move on. Are there any tips to know when you’re ready to move on to the next step? Because if I’m not sure if I should stay in the same place I am and if this is the maximum I could perfect for a beginner level. I hope you guys understand since my vocabulary or grammar isn’t perfect. (I posted this post here sadly because it wouldn’t allow me to post this anywhere else for some reason)
