It looks a bit blurry, the handle is too thin, and the top of the hammer looks smaller than the bottom, creating visual imbalance and making it look like a keg instead. I'd suggest using very thin white lines to give some extra shine to the highlighted areas, which would also help with blurriness. I really like the fiery version, it looks cool.
You can't post icons like that. If there's two variations of an icon, either upload them both if they're different enough, of attach the variations to the first post.
