It is in my opinion =)
Anatomy is something which takes time to learn. However, picking angles and panel excerpts or perspectives can improve the joy of reading a comic incredibly! I noticed that people care only secondary about perfect art, they want to feel like they are IN your story, not looking at a pretty picture book with characters tehy can't relate to 
I started to notice the difference with a short story I drew in 2007, where I tried perspectives I had never tried before and made sure I put at least one detailed background per page instead of doing only headshots. Showing a wall clock while people talk instead of those people can change the pacing of your comic completely. A dramatic perspective can make a simple stick figure look like it is in mortal danger, etc =)
The feedback was incredible - My anatomy and stuff were far from perfect (they still are today), but the feedback on the short story was great: I got encouraging comments on the crazy perspectives or the love for details (I researched as much as I could on historic sailing ships, so working with references is a great help!) - and this motivated me to grow even more =) Art is a process of learning and every time you think you're good, you notice how you can improve even more - because the learning never stops 
The most important thing though, as I write this post, is: Have fun and don't put yourself under pressure.
When in doubt with your main story or about starting a bigger project, why not make several short stories instead? Make one in a crazy fantasy world where EVERYTHING goes.
When you struggle with human anatomy, draw monsters or Pokémon - they are much easier than humans, because they are fictional - by doing this I actually improved with human anatomy as well, because drawing monsters (or Pokémon) taught me about stuff like anatomy, perspective and unexpected stuff like "how to draw lightning" or fur texture or how does a character surrounded by fire look like.
All of these things combined make for your personal learning experience =)
Or, as an example, October is the month where all artists go crazy, be it by participating in Inktober or another preferred -tober by choosing a prompt list they find appealing. =)
Ask friends to give you prompts, you will probably get a ton of things that will pull you out of your comfort zone - and this is actually rather a fun part! =) Some of the most fun things can come from the weirdest prompts. Or you could use prompt apps, like e.g. Jazza's arty games app (not free, but incredibly versatile with randomized and fun prompts!)
Plus: Working with prompts that are not your own clears your mind when the thoughts are spinning, it's like putting that vicious circle of "I don't know where to start on improving!" on a small timeout and allows you to relax a bit
