Yian:The problem is obvious because the drawing is a up close view of her face so your lips, nose, eyes, and facial structure has to be superb for this drawing to look good.
actually not necessarily, not everyone 'manages' a perfect image yian, we are always striving but it happens in stages, i think sometimes it's nice to say that too, rather than just say 'it's wrong'. And lets remember, she's a gargoyle!
is this going to stay a sketch? or are you intending colouring it, yian is right that you should get the facial proportions as right as YOU can, are you using refs?
I'm loving the horns!
