I see many ppl are watching your image but no one is saying something about it.
For starters, that's an awful scan of such a good art. Change your scanner immediately! :P
But, luckily there is a PS to help improve the scanned image. I suggest to 'wiggle' some Brightness/Contrast first to make drawing a bit darker and to show some more details of the piece that are hidden now because of bad tonal control of the scanner.
Some would say: Hey, dude, that's a lot of white stuff around there, why you no like background? Are you background racist? Shame on you!
But, I say, to hell with them, since this is a snake head and tongue study, and study sketches like to be enveloped in void.
Only mistake that I see is that you missed the opportunity to make snake's eye the main thing of this drawing. By that, I mean to make it most detailed, shiny, with much more attentions to details. Together with the some wet effect on snake's tongue, that would be two things to attract audience's look and attention.
All-in-all very nice study.
If you gonna continue to work on it in PS (and by that, I mean, to color it), then I suggest to add some blurred foliage as a background, and to concentrate with warm and bright colors on the snake's eye and to add some 'wetness' to tongue.
Good luck in your work.
