Hey I like your design, I see that it's starting to get shape and that's great!
minor critique I'd do is relatet to the helmet. I find that in the close up the feathers look balanced in their height and width, but in the full body shot they're wider and not as high. I find more appealing the balanced design on the close up.
The other thing that took my off is the eagle's beak. I don't quite understand what's going on there; is it some sort of noseguard? Perhaps making it larger so it connects on both sides could fix that detail as it would resemble the eyeguard from medieval helmets. Or completely removing it could work as well, but that depends on it's importance on the overal look.
Lastly, a lot of the heavylifting will be done by the smaller details like paint and patterns in the individual pieces. I'm looking forward to see more progress on your champion!
