I like it, generic or not, it's pretty, nice details with coloring and these spots. :3
And yeah, I can also imagine these dragons evolving somewhere around badlands, mesas, savannas maybe, desert canyons and stuff. Maybe even in other biomes, I mean... red foxes, red pandas, red snakes and LOTS of red birds do exist, even though sometimes their usual surroundings are far from red. XD
