For the two strongest, angriest characters in the series, you just know when these two are put together, they're going to duke it out. There's pretty much no other way out of a confrontation than to let the punches fly. The shading on Bark though is rather underwhelming, especially compared to Knuckles who looks more finely detailed.

The metallic shading on the souls of Knuckle's shoes really catches my eye and, which makes me think he should try adding some kicks to his fighting style because you can't possibly believe that being kicked by a powerhouse like him would not hurt. Then again, most of his strength is in his upperbody but I digress. It's an intense picture that really gets you pumped up looking at it. Great job, it's got a fave.
