It's too big for my taste, oversharpened on the demon side, specially the fire thing, it makes it look grainy. You pretty much brush raped the left side. You could've made the transition of the red color to black a little more smoother, some parts are over blurred. The text is failing tbh, look at inspirational signature pieces to get an idea of how you can place your text that would look good with the flow and wouldn't actually destroy the focal. Also, because of the over sharpened parts, idk what focal you wanted to emphasize, the fire or the face. The rule of thirds states that an image can be divided into 9 parts, therefore dividing your image horizontally and vertically in three parts, each of the intersections are called your powerpoints, try to make your focal closer to any powerpoint as it makes the image more interesting, and appealing. But never put other interesting parts DIRECTLY over your powerpoints as it will create a distraction between your focal point and the other parts of your signature. Remember that your focal should be the closest.
Now, It's not bad, nor it is really good. I'd say it is interesting, and it'll be good if you actually work on it.
