Transformers Movie Designs| Knight Optimus Upgrade

I've wanted to do an upgraded Knight Optimus for a while now but didn't know how to do it. I also wanted to retain his glass chest front until I saw Barricade24's "Optimus Sentinel" custom render and this fan-made Knight Optimus Prime concept video for TF5, it gave me that inspiration and idea to make him. This would be him after getting his knight form.
