This is nice work from you, clean and confident lines.
If you don't mind me giving you a pointer that will go a long way. Don't be afraid to add in some reverse inking ( go in to the blacks with white ink). You'd be surprised how a few little nicks and white lines give the page that added energy. I'll also tell you editors love this type of thing.
The next thing I'd point out is the inks over all are a bit on the light handed side. I have an editor that is more fond of a heavier line. that doesn't mean you have to make your lines chunky. just step back from the image a bit and pick and choose where you can be a bit more heavy handed without loosing your style.
My hot tip of the day: reverse inking is quick and easy but gives the illusion that you put a lot more into the page than you really have.
