I will give you the honest truth. Besides saying "great work", there are a few items that I don't think are working.
1. The chest piece, like HaloGoddess said, is way too big.
2. The cod piece will look better if it is reduced by 10%-15%.
3. I'm not digging the color either. It hides the detail of the armor and make the whole suit a mess. It is better if you stick with one color and then weather it.
4. If you are going to redo the chest piece, I recommend that you redo the gauntlets as well. LD, with lines painted on just look tacky. Look for the HD gauntlet, I believe by Robegenesis. You should also go with HD chest piece. I like Flying Squirel's.
5. The helmet looks the right size. Are you going to tint the visor?
6. You may need to improve some of the paint jobs. Rushing it will just make the whole effort of building go to waste.
7. I suggest that you try to finish the armor with some bondo.
Don't take this negatively. I think you are doing some good work. It just that there are some areas you still need to work on. I, myself, is still continuing to learn on how to make the armor perfect.
