Sorry not a big fan of this, it kinda looks very simple, almost vectorish. Try adding some more colors in the next one, like different shades of flames, in places where there should be lights and darks. Also, dont use to much of one color. You overpowered the whole painting with black, or the dark color, and it has no reflection of any part of it. Very flat. Sorry, i dont like it. Try it again?
Then again i dont know much of oil painting, ive done acrylic only.
