I think the biggest problem with the lines is the lack of weight to them, they're all completely uniform in width which works fine for simplistic cartoony forms but when you start to get more detailed they really start to look off.
General rule of thumb is objects closer to the camera should have thicker lines then those further away, objects in shadow should have thicker lines then objects in direct light. (I've also found that inking like this forces me to think of my pictures in more three dimensional space which is always a good thing)
It will just help your picture to look more three dimensional. It looks like you're inking with the pen tool in photoshop right? Another thing that is a great help is to select 'simulate line weight' when using it, this will make the lines taper towards each end with the middle being the thickest. It can take a while to figure out how to get this to look decent instead of a whole bunch of tiny spikey lines (In general try to keep the pen line pretty long before you stroke with it) but it tends to look a lot fuller.
