Edits of artwork

It has come to my attention that from time to time, individuals download my artwork & shift it off as their own. What I've done is, I have photoshopped minor changes to some of my work. The pieces you see on here are slightly different than the original. Take the pastel piece of the John Tyler landscape I've posted. There's something in the right corner of the original that I photoshopped out of the piece you see here. If you'd like to see the original, you'll have to email me.
