From life sketch attempts

It was very bizarre for me to not do ANY sort of Photoshop to this. No slight repositioning of sketches, no removal of eraser dust, nothing, but I don't yet have Photoshop installed on this computer. It's so nice to be able to upload from the same computer as I scanned it on though! _{Even though the internet connection is inconsistent and was out almost all of yesterday and most of today...}

Tried to do some from-life sketches of my dog. It's frustrating and I don't get how to do it I have problems simplifying, so maybe that's it? And the subject just keeps moving. So only two of these are any good: the upper righthand one and the back view.
He's a German shepherd with a corkscrew tail. ^^ Though some call it an "ugly fault," I find it adorable and a bit unique. He doesn't -have- to conform to the breed standard for showdogs.
