Awesome suit design!
I think you could define the edges more by adding highlights. On top of that, you could try adding textures such as scratches and dirt.
One thing I like to do is find a random metal texture on google and put it in overlay and set it's opacity lower. You can always mess with the layer blend modes! See which one gives you a better look.
I'm sorry if the advice and feedback is what you're looking for since I am relatively bad at giving feedbacks 
No, your advice is pretty good! I agree with the texture a lot, I can see now how plain it is without texture. I'll give it a shot! Thankss!!
Nice drawing skills!
Like it!
Thankssss!!!!! ^_^
I realized that I was going way ahead of myself on this concept design or character design thing by tackling themes that are I guess a bit advanced for me. I forgot the fundamental of going small first, baby steps if you will. That said, I made this "Garebear" through Zbrush and Photoshop, and I am really happy with it cause for the first time, it feels like I didn't try hard, and it looks and feels finished to me. I know I got a long way to go, so practice, practice, practice. I hope you guys like it, and feedback is always appreciated!
Cheers!

Putting together what I've learned so far. I know I'm still lacking a lot of stuff, like design, finesse, etc. I'd appreciate if you have two cents!
Cheers!
