Killer rendering! I think the design could use a bit of simplifying, and perspective is a bit shaky. I really like the gold blade over the rear end though, I have something similar (in spirit) going in my internship project.
Really nice rendering Hoang. I have to agree with Kirill on his comments. However, I do like the forms you've taken on. - Merrill
Holy eff Hoang! Way to slap us in the face with some improvement and a new style! Love it. The complexity and rendering style seems so Russian to me haha! The lines are a bit complicated like they said but I think you balanced it nicely with the soft forms in the body side.
