The perspective is off on this page. Not your fault. But when an editor sees your inks, all they will see is the artist's mistakes.
So, in an effort to level up, I'm moving into sequentials. This the first page in a series of Zatanna pages penciled by ink4884 (I believe his name is Peter Ngyun, but I most definitely could be wrong on that count), and the original pencils can be found here.
I don't know much about inking so can't help you there, but i do agree with Shannonh.
There are so much things wrong with those pages (perspective/anatomy wise) that i would've suggest you simply not to use them.
Covie, I know it's only in its early stages, but I want to point out the smoke wisps coming from her hat at something to focus on in your inking. These types of forms need to maintain their energy and this is where variations in line weight play a key part. It's an area I struggle in greatly and I mention it here because I feel you're progressing rapidly with inks and would like you to pull those wisps off well. Static lines will make those energetic forms deaden - it will make them very flat, so really pay attention to them - focus on their depth and movement. As far as I'm concerned, they are what could make or break that panel for an inker.
P.S. - the other guys are right - there's lots wrong with that page that's on the penciller, but as an exercise they're fine. Her name is spelled wrong on the marquis as well. Ink is a good artist - I think he actually got picked up by DC, so I know he's not all that bad - DC certainly likes him enough. Hopefully editors (and possibly good inkers!) will have had him make adjustments to pages like this (or made the adjustments themselves, in the case of inkers). Either way, have at it!
