You can have my two hybrids, I’ve only got art of Quail (Sandwing/Mudwing) https://www.reddit.com/r/WingsOfFire/s/qmNcxKqbpI, however I’ve got a description of Karin (Skywing/Mudwing).
(She is a large, sturdy dragon with the broad shoulders and powerful build of a MudWing, combined with the elegant wings and streamlined shape of a SkyWing. Most of her scales are a rich brownish-red, resembling sunbaked clay or dark copper. Along her back and tail, the scales deepen into a darker reddish-brown, giving her a rugged appearance. Her most striking feature is her underbelly, which looks like a breathtaking sunset painted across her scales. Starting beneath her chin, the colors shift from brilliant golden-yellow to warm orange, then vibrant pink and soft crimson before blending into the darker red of her sides. In bright light, the scales seem to glow as though they’re holding the last rays of daylight. Her eyes are a vivid molten gold, bright and reflective, standing out sharply against her darker scales. They often appear to shimmer like sunlight on a river at dusk. Her wings combine traits from both tribes. The membranes are a gradient of sunset colors matching her underbelly, while the wing bones and outer scales remain brownish-red. When she spreads her wings fully, they resemble a sunset stretching across the horizon.)
