my new model please identifying my error and give me advice for best quality

Your model has issues with textures, uv, topology and anatomy. As for animation and rig it is obvious that also everything is very sad.
Phrase from description "very higly lowpoly quality" sounds cool of course but absolutely doesn't match to reality.

By the way, getting reputation points by writing comments to your models (for example as here https://www.cgtrader.com/3d-models/scanned/various/pear-fashion-gold-pendant, https://www.cgtrader.com/3d-models/scanned/various/gold-nugget-ring, https://www.cgtrader.com/3d-models/scanned/various/ring-fashion-gold, https://www.cgtrader.com/3d-models/furniture/sofa/new-style-reclaimed-wood-sofa, https://www.cgtrader.com/3d-models/car/luxury-car/audi-rs6-avant-2017-new etc.) looks very stupid and ridiculous.

thank you so much i can be try these thing next time

Explain to me please, how is possible that this model (https://www.cgtrader.com/3d-models/car/luxury-car/audi-rs6-avant-2017-new) at this price (3.5$) is profitable for you ? And how is it possible that it is the same as this free (https://www.cgtrader.com/free-3d-models/car/sport-car/2020-audi-rs-6-avant) model wich is originally stolen from Squir ? https://ibb.co/cyNyf2c
