Of course this is true for basically everytime but in this case, we are a website who gives points for efforts. So we need to evaluate the technique vs the result. I'm a big fan of minimalism because I'm the first to think that you don't need to put a mess in something to be concidere as a piece of art . But in this case, this is not a clean result or something like that. Minimalism is something that, put together, we don't see anything that can be added. But with this sig, it's looks like a unfinished collab. And the fact that the font is really noobish, it doesn't help. The render is kind of plain and the bg is boring.
Of course the sesult is more important than the effort (most of the time) but in this case, the result is not that good so and I don't think you can claim the effort on this one too.
