My vote is going to Galukxy for a few reasons. First of all, I felt both entries could've worked with the stock a little more and really tweaked the colours and stuff a bit more, however Galukxy managed to make a fairly low quality stock pass for quite a polished finish which is a big positive. While Signomi had tweaked the blue colours in hers beautifully, the colour scheme as a whole felt a little disjointed, where Galukxy's was more balanced, but perhaps a little too cold.
Anyways, in the end I just felt like Galukxy had a nicer looking result.
