I think it's fine as is. This next bit of personal critique is more for your future works, than this one(which pretty much summarizes my whole critique here, if you wish to skip the non-sense):
Please, please, please try to stray away from the aloof big muscle guy pose! You have a wonderful way of choosing colors, but the only thing that holds most of your pieces back is the muscle-guy anatomy. This character could have done well without the muscley arms, and that static pose.(in fact, I think it would work better with skinny arms, provided the character and possible funny message.)
Just as a refresher, these are the pieces that stick out in my mind, from your gallery in Pixeljoint, that seem to have this very same issue and haven't let go of it since!:
1.
Stout: good piece, small but readable...unfortunately, the start of a safe pose...maybe too safe.
2.
Grunt: Massive improvement over the original(though I'd wish you'd left the original in the gallery somewhere for others to see how much better this has gotten)...but noticing the pose is still in this safe, static pose...maybe the next will change.
3.
Gluggernaut: Starting to see a problem here...it's not so much the technique, but moreso the fear of branching away from what's comfortable...Digging the drowned out colors, to set the mood for the scary character.
4.
Tsu-Moe: the Pros? Great technique, per the norm with you. The Cons? A near replica-pose of your previous Grunt and Gluggernaut character. Mainly, it's still lacking in Dynamic-ism(is that even a word?), pose-wise.
I know you do pixel professionally, I just wish you'd show us more variety in some of your monsters/humanoid characters. For most first timers, seeing something like this is impressive, and SHOULD impress them. But for me, I've seen your art for a while and maybe that's a fair reason as to why I feel this way, but the tired pose detracts so much from how much better this could be.
Also, I'm not trying to be a dick. I've seen your portolio, and it's great. But this big guy pose thing seems to be bleeding into your other mediums as well.From one growing pixel artist(err...artist in general, I suppose) to another, I just think it's good for us now-growing-old fogies to tell each other the truth, for the better and never for the worse. At any rate, and silly rants aside, I still think this is a fantastic piece!
