Harmony - Troop Symmetry

Here are my suggestions: 1. Remove the shine from the wings, as it looks like plastic. 2. Maintain the color scheme of the Haven upgrades, specifically blue - white - red.

The feathers should look more natural for a light dragon. Or better yet, come up with something else instead of feathers... Sunbeams, for example ;) The first option is not bad, though.

No, the second option is better than the first...

By the way, sunbeams could work. A yellow, crawling texture (e.g., sunbeams on a map) that is not affected by the surrounding lighting would be suitable.
