I don't mean to start a war or anything but I use this (https://unnuuk.deviantart.com/art/FeralHeart-Wild-Interface-and-Podium-Overhaul-617057130) interface, and it seems that you've just edited it. Did you ask the creators permission to edit it? If so, then that's fine, I really like the look you've given the interface. I just wanted to make sure, and you should also give credit seeing as you've shown the interface in screenshots.
But as I said, I love the rainbow edits you've added.
Going along with Arreze, it's almost like theft for you to not credit the original creator of the interface unless they've give you permission and there's proof of it. But if they have, then like the others I really love the rainbow look added to it. I don't know why, but the colors with the gray is pleasing to the eyes.
