None of the imagery on this site is original, or at least created by me. As of the date of this writing, the only image I have is the header. I did a google search to find the owner and came up with the following, which I’ll assume is the image credit:
Everything is in Russian on this page but from what I can tell, there is just a bunch of free artwork here for download, though I’m unsure if there are any royalty concerns. I’m using the image here because I absolutely love it.
If you own the rights to this image or you know who does, please feel free to contact me immediately. If I can get your permission to continue using it, that’s much appreciated. If you’re not into it, I’ll take the image down immediately and figure something else out.
