This took me upwards three hours, a lot of wrist pain, and almost the entire contents of a pen. Very happy with it =D. Compare to the original picture used as reference:




Also, for practice of distance prior to making this, I also drew this:



I'd appreciate some critique and comments.

very cool stuff denim, looks great

lol thats really cool bro. keep practicing.

Being an artist, I could sit here and pick this thing apart, pointing out every little flaw, but I'm not going to do that, haha.

The main critique I'd give is just to try to pay more attention to the angle(s) you're drawing things at. It's the kind of thing you need to notice early on, especially when you're using pen, since you can't simply fix it later. (At least not as easily as with pencil.)

Also, while it's fine in most parts of the Jawbreaker piece, maybe try to clean up details a bit. (For example, the right guy's jacket. Areas like around the collar are a bit jumbled and covered by the scribbles of the shading, so you can't see the folded collar part very well.)

Other than those two things, as I said to you last night, it's a pretty good piece.
The distance practice piece is also pretty good, aside from the minor flaws I pointed out to you last night. More or less, the effect is pulled off well. The only advice I can really think to give for something like this, though, is just to try various practice pieces, using different angles and such, to see what kinds of details result in a more effective distant appearance.

Those are both really good. I’m more a fan of the second / distance one, personally. Can’t really explain why I like it more though (and I’m not going to try since I’d probably end up confusing people in the attempt. >.o).

Anyway, you’ve been doing a good job with your drawings. Keep it up. =).

There's something I like about the train tracks one, can't say what just now. First one is pretty good, but I agree with Chalryn you just gotta watch some of the angles. That aside I was quite impressed with it.
Extra credit for being able to do that for more than an hour! My attention span seldom lasts that long when drawing which is why you can draw that well and I can't
