It looks a lot better now, major improvement from the previous one! However, if you want to make this model to resemble the original one even more, you should change the feet and bulk it up a bit. The torso also looks a bit too high for me compared to the original. The shoulders should be bigger too, I think the previous version had a better shoulder armor and joint. Ball joints are good too, but they're kinda exposed and hard to cover. The hands are superb, and yeah...some coloring would be benefical. Otherwise it's still great! Good job!
I like this! A bit rough, but it adds to the military hardware sense. Feels a lot like Armored Core/Front Mission styling. My only recommendation would be adding a little accent coloring. Nothing drastic, just enough to add some spice. Just a suggestion!
