well the render is too big imo
the text looks weird imo and doesnt work at all
he doesnt blend at all to the fire in the back
and since i know the render cuz i have it i know that like his face is clear and the body is blurry ish and since it is blurry u should sharpen it cuz it kinda looks LQ imo
so since like nothing works u should redo it

try to smudge add c4ds or something cuz its way too plain also it looks like u put fire in the bg then pasted the render and added text and a border which also looks not that great
i give 2/5 since ur a beginner but u should look up some
TUTS to get better
