Artist in question did indeed provide me with .PSD's of the art commissions I got from them. The files are admittedly confusing in the amount of layers they contain with minute changes inbetween them, but there's clearly evidence of the artist's own efforts... such that if I had these I likely would not have posted my last journal. So, I am sorry to them for that.

I asked a few people (artist friends included) for their opinions, and they pointed out some details that still leave some lingering suspicions in my mind... I'm not sure what to believe one way or another other than I just want to put this behind me and not think about it anymore. I won't be reuploading the artwork in question.
