Work on the silhouette; Its too chunky. The details are way overdone here and lack focus. Think about how buff and strong the character needs to be in order to wear something this heavy.
Buff character wasn't what they asked for, and overdesigned is exactly the aim of these mecha character suits. The smallest shapes were kept to a minimum, and color/value contrast is used to have the face as a clear and obvious focus.
Really nice concept design
