What a unique name – love that. I also like the design and pose. Rusley could be a counterpart of a character I designed several years ago. How cool is that!
Your concept sculpt seems like it’s headed in the right direction: Pose is strong and the features/details are starting to take form. Basically my only advice is to keep working on it; push it further into being a polished, finished sculpture. Right now you have a very promising WIP.
