Very nice, good to see new people into art yes yes, the details are fine, but the form/shape is rather..basic.
It looks flat and the blue lighting should also go along the bottom of his lips, this will make it stand out more. Your top light source also seems like its defined in the wrong way, the wrong direction.
EDIT: The blood on the lips is..also too..thick like rubber jelly or something, try to stain the red/blood over his lips then have slight layers of saliva over that.
Apart from that, id like to see more from you.
