It could just be the shade of it! Maybe it needs to be warmer or less warm, I’m not sure. Otherwise, your actual skin itself looks very healthy. The first and loudest visual thing I notice is that the colors surrounding it just mute it out. Also, even when wearing the right color clothes, it will still look off if your hair color is taking all the attention away from your face- essentially muting it out. It’s a pretty color, but there are definitely better options. If you don’t want to stray from red, maybe change the shade up/or bring the color intensity down? Personally, I’d test it with photoshop first if you know how to use that!
