I say 1.3 and 1.4 are the best out of Tanya's collection.
The G's and I's in these circle are just not enough to resemble "Guns of Icarus", however this is where 1.3 and 1.4 succeed. Your font, font alignment, image placement and color; it all reminds of the original "Guns of Icarus"-Logo and thus reminding everybody what this "Hepheastus Challenge"-thing is for and about.
The circle is certainly nice and is a nice idea, but what did you have in mind for that circle? To look pretty? It vaguely reminds me of this leaf crown that the old greeks used to have on their head, but that's it.
As nice as these look, Hepheastus also stands for fire, lava, some metal that is glowing hot in the process of being turned into something new. DrPanda has visualized this very nicely, but then again, that is a picture and not a logo...
What I want to suggest to you, Tanya, is: Bring that Fire into play for the logo. Even though the color is a nice choice, it lacks a second one. Currently it's a dull logo, missing that something extra to make it complete, that something extra to make it hot!
