I need some feedback on this one cause i showed it to a friend and he seemed to be confused on whats going on here
It is still in pencil so i can do some changes but the paper seems to be holding on the last breath and it got teared up in couple of places so i if want to finish it i would need to redo it anyway on a new page

When a drawing is hard to understand, it's almost always due to a failure in composition. In your case, I think you're trying to cram too much information into a single page with very limited real estate. Try to keep things simple and organized.
First, decide on a focal point for your composition (the knight dude in the case of your drawing), then divide the composition into background, midground, and foreground, and frame the composition around your focal point.

In this very quick (and shitty) example sketch I made, I delineated the BG, MG, and FG using the hydra heads, and also used the heads to frame the focal point. This drawing still isn't great, but it's a decent foundation for a finished drawing.
Additionally, you're also trying to do too much in your drawing
— you're depicting dead hydra heads, trapped hydra heads, hydra heads attacking, hydra heads being attacked, hydra heads about to attack etc. It's too complex both visually and conceptually. Again, keep things simple. In the example sketch, instead of trying to stuff a ton of information into every blank space, I simplified everything and just made the knight defending himself while the other heads are readying to attack. It's clear and adds suspense as a bonus since the knight is on the backfoot in the fight.
One more thing you should consider is the silhouette of your drawing. Take all the positive space in the drawing and make it (or imagine it) as one solid color. If the action in the drawing is still clear even after being silhouetted, then your composition is solid.
Obviously these are just suggestions, not hard and fast rules. So just keep these things in mind while drawing and take or leave whatever you think is necessary.
Hope this helps.
