The cloth and the patterns on it are absolutely amazing, but the rest could use some work honestly.
What do you mean specifically?
Well, the metal is very flat. It looks like it got a wash or 2 but not much else. It needs some more highlights and shading, and adding some colour and or weathering would also help.
The skin looks like it has good transitions, but a bit more contrast would help, as well as colour on the cheeks and nose.
The horse could use a bit more contrast too, as well as a bit of hair texture.
Thank you very much for your comments and attention to my work. Unfortunately, I can’t attach more photos with large fragments of the horse and the rider’s face.
