Really hate my "style" and my anatomy is all over the place, can anyone help figure out where my weak spots are?

I cant get over the leftovers from the rubber that look like youve drawn a butthole on the guy bottom right

Omfg i didn't even see that, im dying
Yep - me too!
Glad I'm nit the only one who noticed that lol
Well, now I can't unsee that

I'm just really tired of trying so hard to become better for the past 8 or so years and still feeling like a mediocre artist, I know that's dramatic but there seems to be an invisible barrier I can't seem to break past to where I'd be happy with my style.

More examples of my art

here

And a bunch on my instagram

Any consistent problems or issues you see? Be honest Im a big boy and can handle it

I like the style, it's very emotive and expressive. I can tell you have fun making art and it makes it fun to look at. A lot of your pieces on instagram feel like an experience to partake in, and I enjoy that. Here are somethings that prove to give returns to an artist of any years; fundamentals.

Draw from life. Basic things to start, but something you don't mind looking at. The fun is what your eyes see, the object, so pick one you like.

Use reference until you don't have to, then keep using it. I see that the more you rely on imagination the more amateur it looks to me.

Figure drawing; gesture/studies. Anatomy, proportion. (weakest)

Perspective. (strongest)

Shapes. Form. Shadow. Light.

It has been fun looking through your work. You are really quite good and should be more patient with your progress.
- Thank you I'll keep at it, I just finished a huge project so I'm a bit off my training schedule but hopefully Ill get back on soon

How much training have you had?

How familiar are you with the fundamentals?

Have you done any basic still lives? Humans are very complex creatures made of many shapes. Boxes jars fruits etc are much simpler and help to teach you how to deconstruct an object into its component shapes and how light interacts with them.

I've done a few years of art school but never graduated, did plenty of life drawing classes, all the fundamentals and I actually do practice them once every two weeks. When I had more time in the day I would do 30 mins figure drawing and 30 life drawing a day, I've since fallen off of that though.

I actually feel like light and color are my strongest areas, but anatomy and keeping proportion I struggle greatly, and if you mess up the form then no amount of shading is gonna make the piece look right as I have found the hard way
- Your figures look flat because you're drawing what you think it should be rather than what it is.
  
  I would recommend drawing through on the perspective and some practice with making figures out of simple geometric shapes.
  
  Also, I'd consider getting one of those posing mannequins and an anatomy drawing book to give you more examples.
  
  Your poses are somewhat complex from a perspective viewpoint (parts pointing and angles towards different planes). You may want to try some simpler poses like standing with arms down to get the basic proportions right.
