While I think the line strokes look fine, albeit some of them are wobbly, what you really should try working on is making the line weights consistent, since some of them are very thin while others are very thick. They don't all have to be the same length, but some of those thick lines make the thinner lines look rather scribbly.

I dunno, i think he actually wanted that effect to put an enphasis on the fattest and closest parts of the dragon, which imo works pretty damn well.
I mean, it's not like those lines are random, it's an effect he wanted to show and it very nice :D

While that may be, the way it was executed is rather sloppy and inconsistent. The thicker parts look more like ink being spilled on accident and some lines overlap twice ( Such as under the belly ). I'm not saying it's bad, but there's definitely room for improvement, one of the easiest ways gaining more control over his strokes.

this is true, line width consistency is one of the things i have the most trouble with when making drawings. The way that its working here is basically because the program im using has vector capability. this means that i can go back and alter the width of strokes after ive already drawn them and i was messing around with that. i noticed that some of the lines were ultra thin, but as i'd already been working on the thing for like a half hour i basically said screw it and put it in scraps.

the tone doesnt stay within lines too, if you look closely
anyway the more you know.

I did notice the vector lines, it's good that you're taking advantage of that as well. Hopefully you'll get the hang of it, I look forward to seeing you get it down well!

Woot, i dig that inking, has a lot of character to it. Also, shading is amazing.
