I saw your gallery, beleve me it's really great, and you're practising more than me so don't lie to me
'cause I know what I'm saying
your strong side are eyes, they all in your pics are truly amazing and have great depth. and I admire hairs, I've no patience for this... I've got only one advice - you can shade it more bravely, don't be afraid of soft pencils like B6-B8 and make good background.
and don't make me mad with saying you're not good and just... draw!
