*Insert Soul Eater reference here*

This is a good realist drawing and I see how you used varying pencil shading to give depth and texture to the drawing.
However the drawing feels a bit lacking since it isn't even a full head and without any sort of outline, color, background, etc. it's a bit difficult to find where the drawing really ends since it just seems to fade out. Finally (reference) the face is a bit unsymmetrical, the right eye appears to be leaning down, the nostrils are clearly unequal and this leads to question whether or not the mouth is out of place.

I admire anyone who can draw like this given the difficulty but given your age at the time I assume you were just messing around and were not aiming for perfection.
