Hmmm, I think I'll try downloading your skin and working with it. I know if you have this type of problem, others are bound to have it as well. (who knows, I may encounter the problem myself in the future and be forced to fix it)
I think I fixed it! Turns out, your Alpha Channel had merged with your head phones. So I removed the alpha channel and re-added it, then changed your headphone shade a tad to prevent it from mixing with your Alpha. I uploaded it as my character and it worked. Here it is attached, try it!
Yeah, that definitely seemed to be the issue for the skin.
The pixels I removed were in the highlighted "dead" area as they called it.
The forums are full of people having this exact issue with the skin. I filed this bug report a long time ago but the moderators just aren't doing their job in fixing it, which annoys me badly. Would you mind sharing your experience with this skin in a comment under that original bug report to back it up once more?
