if you dn't mind I'd like to use this as my background on my laptop
Please feel free. That's why I make my pictures! Go ahead and download anything you wish.
Awesome Thank you I'm new to deviant can you help me learn how to do things like that
No problem: to get the full size of pictures on DeviantArt, assuming the artist has enabled that feature (which I have), just look to the right of the picture and you'll see a "Download" button with a green arrow icon on it. Click that, and the image will open in a new window in full resolution. Then just right click and save it as normal
