EDIT: Oh hey, a DD. Didn't see that coming. If you guys are here because you dislike ponies, sorry. I had no control over this.
Well, at some point, I think it's gonna be practical to compile all my icons into one downloadable zip file in case I make a lot lot more of these in the future.
Also, please excuse the differences in quality and style and the general incoherence as I made these over a time period of one month for practice to figure things out.Keep an eye out as I may revise this deviation to include future works whenever they are made!To download, click the download button to the top-right of the screen.
There will be a zip file which contains varying sizes of every icon of the mane six, including 100x100, 75x75, 50x50, and 150x150 which is a scaled version of the 75x75.No permission required to use. All I ask is common courtesy from others to not claim credit for making them, so please don't upload this somewhere as your own work.

Older stuff (which I would personally consider deprecated), and deviation pages for individual icon sets can be found in my gallery if you dig deep enough: [link]
