Why does it look bad?

I'm pretty new to drawing but recently I decided to do a bit more ambitious drawing. It's the first time I've tried to make a face other than the front but I feel like it looks terribly wrong or doesn't fit, maybe it doesn't even express what I'm looking for but I'm not sure why. What do you think?

Note 1: I know it's not a good sketch but as I said, I'm just learning and I'm trying to do things well but above all in my own way, I've already done some practices on paper and I try to apply what I learned without copying or tracing, just using references.

Note 2: I accept any type of criticism, advice or opinion if it is constructive. Thank you very much in advance.
