Here’s my cougar! I did retopology once again, then painted the texture with a stencil using tons of cougar photos, and the result was quite satisfactory. Also, bald spots in the particle system are not as noticeable if you paint the texture this way because it creates an illusion of hair. I must admit I exaggerated its muscles because I wanted to practise sculpting more. I used Rigify to add a rig and pose my sculpt, and then I just tweaked it to eliminate weird stretching. I didn’t spend much time on this project and didn’t put too much effort into it so there are a lot of things I could improve. I’m rushing to finish the beginners course so I could finally start the character creation one! 
The HDRI was way too large for my scene. So I made a round background using the same image and placed it behind the sculpt.
