Ah the scratchy lines... I used to have those. For me it was a problem with confidence and me trying to get every line exact by stopping the line/Stroke short every second but I just ended up screwing the lines up by doing that. It could also be the way you hold the pencil, from the looks of it it looks like you're holding it as if you were writing words on a piece of paper. I'm not sure how to explain it on the computer so simply put, There is a different way of holding the pencil. If you have an art teacher I would encourage you ask them how to hold a pencil when drawing, you only learn from what you ask and acknowledge. You can also ask about the "flow" of a piece, or how you guide someones eye through your work the way you want them to. I say this because it looks like you were going for a comic book page type of style, and this is how comic book creators create good illustrations. Something else you can ask about is the depth of a paper, or how "3D" something looks on a 2D surface, because right now the way you framed and positioned all the character makes it look kinda boring. Though this is ambitious for someone who had just started drawing, your anatomy of course could use some work but thats really good for where you're at, so keep working hard on it and I'm glad you didn't also flip the fight scene upside down that's a +1 in my book. So AWSOME WORK, and please KEEP ON GETTING BETTER! :P
