The thing I love about your MOCs is how you create an overall mold and shape. I love the shaping of this one especially. I think it’s the taper - too often, I see MOCs that seems to rectangular and static in shape. The way you use parts always contribute to a shape, and that shape flows.
The little protrusions from the golden wing blades do kind of ruin the shape coming from the back, but there’s nothing you can really do about it and it’s a minor complaint. I also get what you’re saying about the gold circles - the ones on the bottom wing. They’re flat and round, while every other gold piece is either angular or has angular texturing on it (like the Bohrok shield-turned chest piece), and so it feels slightly out of place because it betrays the otherwise cohesive design.
But those are minor complaints on a really great design. I think you were right with sticking with your gut. I’m not as well versed in MOCing as the rest of the cast, but I think you made a good call.
