Nice work! This is wonderful: I love your style, and you evidently have great artistic talent.
These panels are very good, in my opinion, so it is worth pointing out a couple of things that will make this a lot better and turn it into the kind of quality work you can see in professional comic books.
The first thing that jumps out at me is the cross-hatching: too much and too rushed. Try to use a thicker line weight for the shading, instead of hair-thin scribbles. I think the foliage in the last panel is a good example: It will give the forms a much more solid feel. Follow the contours of the shape with your shading or hatching, don't just scribble the shading in any which way.
Another thing that bothers me is the fog on that last panel: it is the only instance where you have gradients in these two pages, and I don't think they are necessary. They break the feel of the linework you set in the other panels, so I would do away with that style of fog. You can replicate it with black and white lineart no problem.
Keep at it and please continue to post, I want to know what happens next!
