Okay, it's Realmwalkin' time
So looking at your comic, I can tell you have made quite some leaps when it comes to the art. There's a lot more polish on your characters and the panels are more clear. This one in particular is my favorite because of the shading and pose/more dynamic approach
That said, I do still have some issues to point out.


The backgrounds and props feel really flat, and I noticed most of the time they aren't even in the same panel as the characters. They are nearly always in separate panels. This means your characters never really interact with the environment. And yes, while Merlin does technically interact with the environment by fixing the stones it doesn't actually feel like he is there, there is no shot of him in the same panel as the stones. The only way I know that he is fixing them is due to the purple on the rocks and him saying he is here to fix them.
This is one of the exceptions but the background props are still not nearly what they could be. The perspective is shabby and it doesn't really sell me on where they are other than maybe a village. Because there is nothing else here. No roads, no benches, trees etc. Just houses and some dots for stars
I would suggest that you try to work on your backgrounds to make the world in your comic feel more alive. Yes, characters are important but without some interesting set pieces it is as if they live in a blank canvas almost. I recall some people saying that you should treat your backgrounds as characters.
Now there are some other things that I could point out like how you could make use of different angles to sell the action more (you have action listed as a genre for Realmwalker after all) but I think upping the background level has more priority here. You could make your backgrounds more interesting by adding more props to them. Does that mean you have to draw every blade of grass and leaves? Nope! You can just use shapes instead!
I grabbed this piece of Adventure Time online as an example. If you look past the shading and lighting and purely focus on background objects you can see some shapes in the background.
As you can see, certain background elements are just simple shapes. The small trees and the mountains are triangular, the boulders are round, not quite circles but still simple shapes and even the plateau with the city on it can be broken down into cone shapes.
Now I'm not telling you how to draw your background, but if you want to spice them up you could always just use simple shapes to convey objects easily and still have some more substance to your backgrounds. Right now they are mostly looking empty and could use some life in them.
I hope this is somewhat useful to you
