Captain,
The bird in entry #55 has a shadow behind it, just like it did with the gold color however entry #54 and #53 has a glow around. I believe the shadow in #55 does not work as it did with the gold color. The glow in #54 and #53 works better as it produces an aura effect around the bird. As you might notice, the bird #53 has a lighter background as the gradient is centered around the back of his head, while #54 has the lighter parts more hidden behind the bird which makes the wings less visible. Just wanted you to see alternatives and possibilities. Other than these details completely changing the background color results in changing the color of "Strongman" and "Private Reserve" which then leads to a whole change of current color scheme. Of course if you wish that is an option too but as far as I tried different colors schemes they did not work as they do in #54 or #53.
Open to any other suggestions.
Thank You
