The model might be old, and approved already though, but I can't check, so sorry if it is.
But, if I can, I suggest that if you can't make the flames bigger, at least make them higher. They're currently at it's arms level, but they should be higher and even right above them. Sorry, I can't provide images to argument my point, but good old gen2 artowrks depicts it with its fire all the way to its "shoulders" (where its arms joins its body).
But nice cool/scary-looking model anyway, nice to see ya keeping up making more and more models.
I only give advice, take it or leave it.
I did my job, now do yours, a choice.
I'm weird, so don't take me too seriously, I'd feel bad for you.
Unless I say it, I never mean harm, it'd make me look bad if you think so.
