I asked you for the color scheme because it was pretty hard to criticise a sketch.
By the way, this drawing got my attention because of the style of it.
It's not ground breaking but it feels different in some way or another!
About the drawing...
Everything looks pretty much correct except the eyelashes and the hand.
The right eyelash in particular is still on top of the eye, even if the eyelid is closed (just a little mistake, nothing THAT wrong).
The hand, instead, has a problem with the thumb as it doesn't look in a comfy position.
I would have drawn it in a more extended position instead, it looks bdaly folded here.
In the end is a very cute little drawing. You just need to add atleast abit of colour to your drawings or they will easily be marked as "sketches" and ignored (which is a shame).
Keep up!
