I don't see anything wrong with posting the squirrel pic, it isn't perfect however once learnphotography has some more experience behind both the camera and the computer it'll make a nice pic.
Judging from his name he's here to learn, like we all had to.. so that makes this the perfect place to post it.
learnphotography, I can only guess from all the noise that it's taken at a higher ISO than the rest of your pic's. The first thing that I'd do if I was you is take the camera off of Auto ISO, or at least restrict it to ISO 400 and lower.
It'll give you more control. You will have to learn how to pan (follow the subject with the camera) however it'll add top the effect of the pic, by giving the background some motion blur.
I hope that you don't mind, I did a little tweaking on it, plus removed the cable.
