You have a solid base to work with but there are some adjustments that I do recommend doing. You should take note of your character's center of gravity because right now your character feels a bit unbalanced. I adjusted the stance of the legs and some proportions to make it feel more balance. For the textures and rendering, I think the skin needs more value shifts, cause it feels a bit flat right now, since skin reflects light, I added some lighter values to render the face. Your fur rendering is fine but I would recommend simplifying some parts and separate them into bigger clumps and shapes. For your cloth on the waist area, the creases are a bit too harsh and that makes the cloth look like it's multiple pieces of cloth, I just smooth some parts out to make it look more like just one piece. Your metal rendering is fine, you just need to increase the contrast and take care of your 3D forms. If you are struggling with the shoulder pauldron, I recommend making a 3D mock up of the design in blender and then pose it in the angle you want, because right now, the one on the left feels like it's getting bent and distorted. Also you can add more dents, chips and scratches on the metal to show more wear and tear. I noticed that the character is missing a lot of occlusion shadow and also sharper cast shadows so I just add those in. Also, I adjusted the fur cape at the back to make the silhouette more interesting.
