Hi-poly head sculpture

You should spend your time learning before trying so sell...

Try to improve your skills ,you are on right track .. almost there :)

In which area should I improve though?

Hi guys,
I think Guido is really right. take a moment, go watch what others do, for instance professionals are perfect references about standard quality products. And come back see what you have done.
I think you have a good base to continue to learn and progress.
I think your head in this state, is not sellable.
But it is in that way you progress, you will begin to see what you didn' t see until now.
Just keep learning, continuing, etc..don' t give up.

good luck.
