Personally, this mini doesn't strike me as a Commander, boss-type skeleton. I think a skeleton commander should stand out a little more with either armor, size, adornments, or a steed. This mini frankly doesn't have much of any of those imo. I feel like there are a lot of skeleton minis that could suit this design better (though, notably, probably not the availability). For example,
THIS guy would suite a "commander of hordes" unit much better.
