Hi!
I’m a beginner at modelling, and I’m aiming to make models to sell them.
This is my first attempt to make a “creature” model with sculpting. After sculpting, I made a lower version of the model (around 2400 faces) with a normal map on top.
The real model is on the right, the low poly model is on the left in the first picture. I’ll let you guess in other pictures. 
You might notice some issues with the normal map. If you have any suggestions about creating a perfect normal map, I’d love to hear.
