As it seems you edit someone skin, hope you asked permission for it.
Now when you skin use viewer to see if anydecals looks good or are highres enough. I see decals which arent high res.
Try to improve every time you skin, read tutorials etctera. And finnaly when you do podt think of it at first. Is this the skin I would like to see public and used by i dont know how many? This skin will not be used very often due to misplaced decals and low res decals. I am not saying you wont put any effort in it but I think you can do better then this.
