War Mech - WIP

Greetings, this its first post for me. The last two months I’ve pushing myself to improve my modeling skills, so i decide to Make a difficult model, so i found a good 2D reference from Keith Thompson Concept art for my personal challenge. Here i post a preliminary render with the 60% of the model completed only with AO. Hope to post new images though my progress with the arms, and then with the textures. All your feedback and comments are welcome to improve this model.
