Hi, welcome to the forums!
Your work is interesting! If you are interested in critics and coments, i'd say you have an interesting mix of superb skills on one side (render of a hand) and some ununderstandable mistakes (forearme anatomy). I say ununderstandable because most people first get better at anatomy and then rendering (it's easyer to learn the anatomy then master rendering)
I think your rendering is so good, you don't need lines, to keep the painting together... The fur, cloth of the shirt, face... It's all really good, why did you stick with the line?
(The comments are based on the Wolf King but i guess they are valid for all three of them).
The presentation is cool. One image of the character and it's easy to see what he is all about, well done!
