Hmm., I can see them in http://pixeljoint.com/files/icons/untitled__r1708219361.png
So.
Thanks for the suggestions, I'll fix it up in a bit.
You certainly have some issues here. I suspect that the file truncation comes from your original file being a png24 file with some level of opacity. I would try making this just a gif if you can't make a png8 file. If the white pixels are not supposed to be there (strays) then for sure your file has semi-transparecy.
*change to a dark theme to see these.
Wtf? it got ripped up in the process of uploading?...
also, there are some stray whites in the piece, might wanna' transparify those when you've fixed it up...sending back for revision...
