@United Joshdom, please have a look at the guidelines in this thread on how to make a good cut-out, especially the parts about 250x cuts being possible if the sources are good and the fact that there should be no more than 2-3 pixels beneath the chin in every cut.

I suggest using remove.bg to get an initial draft cut, since the edges of your cuts are somewhat rough.

Here's a few tutorial videos to help you out.

I will post a new 250x250 image. However on the matter about the chin pixels: I can find hundreds of images in the facepack where this isn't the case.

That may be the case, but very few of them will have been done recently, I'm sure. Wherever possible, we want our cuts to be cut close to the chin or the facial hair in order to have the same kind of type of cut wherever possible.
