too much ground

otherwise great

The lack of any light at all kind of makes it unnatural. The area in the foreground should be slightly lit with some white or something.

The fire could also use some work. Making it whiter in the middle of the origin (from the mouth) can help.
Otherwise, looks pretty good.

it’s replicating the art style of Limbo, which is essentially a collection of dark silhouettes against a white background

That fire could be more vibrant, other than that, a more zoomed in version would be nice. Still like it though.
