I wouldn't say the character is boring, any character if made in the right style can look interesting, I'd say the only thing wrong is the anatomy (which is very wrong) fix that and liven up the animation (at the moment its like an effortless shove and a flash of light) and it'd be great.

in terms of anatomy it can take a lot of study to get it right, so don't try rushing, you need to honestly study it or you could end up missing important details.
in terms of animation you need to put more load and recoil,
typically an animation to make it look believable and exciting it goes in 3 stages,
Load - pulling your body back before a punch, crouching before a jump, jarring your head back before a headbutt, etc.
Fire - extend your arm rapidly, spring your legs out, swing your body and head forwards, etc.
Recoil - arm bounces back, legs return to relaxed positions, head bounces from the hit, etc.

it can take some playing around to get it right, but so long as something has a comfortable load, fire and recoil arc, it'll look interesting.

EDIT:
proof of concept, the character is not boring (though I might have screwed the arms a little bit)
