Looks cool. I have 2 thoughts.
Increase the font size and/or modify the placement. Right now the words look too isolated from one another.
Compared to the artwork, the text looks too clean, Maybe there's some way to incorporate a texture or some other effect to make the gradient more resemble the hand painted look of the artwork. Another thought in that direction would be to use the eyedropper tool to choose your gradient colors directly from the artwork so the reds and yellows of the font match the flames.
