I made this character to add it to my personal portfolio, I will show you how I created it. I wanted to create a humanoid-reptile creature, I searched the google for reference pics for some interesting reptiles, and found a pic of a weird reptile and it was the whole inspiration.
The design proccess was done completely in ZBrush, I started with Zspheres and quickly tried some ideation for the character and it's anatomy, I wanted to mix that reptile with a heroic creepy body, I sculpted a form that I was satisfied with then started detailing, I used brushes like 'standard' and 'move' brushes plus some alphas I got from Pixologic.
I sent the Hi-res model to Topogun for retopologizing and achieving a clean topology, then sent the new toplogy to ZBrush and worked on more details in the sculpt. I used 3Ds Max for creating the seems of the UV map, and then unwrapped it in ZBrush's UV Unwrap with keeping the existing UV seems.
