The eyes and brow lines are amazing. My last "Fantasy Head" sculpture I spent hours on and failed miserably. It was actually inspired by your STILL LIFE sculpture haha. But yeah... I've only been sculpting for about 3 months so I'm not that amazing... yet
Don't worry about failing..I have failed thousands of times but things start working out after awhile. Just keep trying and have fun while you do it... 3 months is to early to be critical of yourself. As far as the eyes and brow lines it took time and lots of reworking but thank you.
