Hey everyone!

I'm learning stylized character sculpting and would love some feedback.

• Left: Original reference
• Middle: My first attempt while following a tutorial
• Right: My second attempt where I tried sculpting it on my own

I'd appreciate any advice on:

• Proportions
• Face anatomy
• What looks off compared to the reference
• Things I should focus on improving

Also, can anyone recommend some good anatomy courses for character artists/sculptors? I'm looking for something that teaches the fundamentals for creating better stylized and realistic characters.

Thanks in advance! Any critique is appreciate
