Not quite. @Bossa is most correct in mentioning that ANATOMY STUDY is key.
The other suggestion to focus on details FIRST is opposite to EVERYTHING taught by ALL the art instructors in my past. ALL of them. Whether oil painting as a child, life drawing throughout adolescence or the year invested learning sculpting from Ryan Kingslien’s Uartsy/Vertex courses.
If I’m to be honest, your displayed sculpt LOOKs like you jumped into details prematurely before solidly establishing a base head sculpt. It doesn’t take an online course to point out… even a 70 year old sketching book from Andrew Loomis will point out certain proportion truths. Eye height, mouth height, chin width & nostril flares are the most glaring discrepancies in your sculpt.
Cobbling together piecemeal eye, nose, lip, ear details and THEN moving it around on a questionable head will be a painful way to advance, IMO. In fact, this blind method doesn’t cover anatomy truths that always needs to be checked on:
- Lower lip corners subducting into the upper lip
- Lower eyelid subducting into the upper lid
- “The bean” at the mouth corners where certain muscles anchor
- Muzzle shape of the mouth region
Once anatomy is understood, it’s the strongest foundation you’ll have when aiming for likeness sculpting. All of a sudden, the MULTIPLE reference pictures you should be using will make far more sense from one angle view to the next.
Lastly, I’ll point out that those sculpting from an anatomy foundation are better capable of conveying whether there’s bone structure or face fat below the surface.
