Yeah, google an image of a skull. Would help you out a lot. And also, I' not sure about the teeth. . .
i'll try remake this other day thx for the advices(yep the blood color is a kind crap) 
1ucas is right, unless you meant to draw your skull thar way... I really liked the colours you choose (though the blood could be darker). Change the shape of it and you will get a great piece!
You should check your references here. Skulls have very particular shapes, and you missed a lot of important anatomical details. You could have studied them more.
The teeths was becouse of the challange of my friend it's proposital
