why is it so wrong!!!

i've been trying to draw this face but......drawing is hard, anyway i felt like i've almost got it. in fact i feel like i got the shapes of the individual features down, but when i put them all together it looks nohting like the original face

you need more contrast to this drawing
like you need to shade more the black parts of the face
work it on and you will understand how it works ;)

Yeah, the reason it's un - shaded is because I was gonna ink it and the scan it to a computer to color it. But something looked off..... maybe m just not sure why

Hey, this might not be helpful anymore because you posted this in October, but... try to look at the photo you're drawing as a cohesive whole, and less like a jigsaw puzzle. Look at how large the eyes are in orientation to the nose, and the ear. Look at the shape of the head- really try to block out the overall shape, and figure out /where/ on that shape all the pieces fit. What you have (or, by this point I guess it's "had") is not a bad start, but I think you dove into doing details a bit too early. Block out the large shapes on the face first, and /then/ whittle down the details. After you get those right, then go onto rough shading. Front-facing faces are notoriously difficult, but you have a great start there! :D
