Warrior dwarf with two-handed hammer

i'v just started to learn 3d sculpting and and my models are not good. I would be very grateful for the criticism and indication of mistakes.

thingview doesnt work for me. The only solution i have, is to link sketchfab:

I will be very grateful to you if you post a photo of a printout. It is very important for me to improve the models.

You can also suggest themes for future models.
