Okay, so a couple of things... 1. A trademark is technically automatic for any mark you are actively using in trade. You don't necessarily need to register it to have it. This isn't always the best approach, but realistically, people are unlikely to copy your logo anyway, so this might be enough to satisfy your risk aversion.
2. Are you worried about consumer confusion from somebody using your logo or a logo that kind of seems like yours (trademark), or are you worried about protecting the image, the artwork, and the style of artwork that go into it (copyright)? 3. The cc-by-nd strikes me as the right copyright license here. You don't care about commercial use, but you don't want others to copy / modify your logo. The artist can give you a separate copyright license (broader, so you can make derivative works), or assign the copyright to you so that the cc-by-nd license comes from you and nothing stops you from using the logo as you see fit (and so that you can also license the logo out differently in the future if you see fit).
