I uploaded some explorations of colors and some slight variations. I simplified the feathers, removing the tree since that might be too complex to embroider properly. In case you still want the tree in the design, I uploaded some with the more abstract tree and clover (#121).
Gradients are usually problematic in embroidery so I think a 2 color design would be best. A good way to introduce a 3rd color is with the surface you're using to embroider (shirt, hat, etc.). I did some options with the dark blue background so you can see what that looks like.
Please let me know how you feel about the colors. If you prefer one of the designs, I can try that one with more color combinations.
Thank you!
