Lovely idea, but I'd like to see the arrows actually sharp and crisp. Try with pure white color, and very sharp edges without any blur to represent them. Currently, the icon is nice but it seems more like a flaming blizzard. This will also counter the blurry flames (nothing wrong with fire being blurry) and further more improve the icon
It's approveable, but it's too generic - that's why I've suggested to try to add more diversity by adding arrows and making it unique. There's a bunchfull of different flame icons, but I don't see this standing out too much, tho it still looks nice and could be useful.
Usually, we wait a little before modding just to make sure a user gets enough feedback from others, but if you think this is final, shout me up and I'll approve it with Useful rating.
I've took the liberty to show you what have I meant with diversity actually, so here's a very quick (took me less than 5 mins) revamp with just added arrows.
If you think you want to do something more, I won't mod this until you do
The flames now have a much more distinctive shape, but I'm worried about too much yellow in there. Perhaps try to add a very little touch of quite bright yellow in the centers, as the fire's epicenter tends to be white.
