Hi Joe Dexter!
Nice one. The blue and grey works well together, and you paid nice attention to details, like letting the blue glow onto the grey parts. Nice with smooth gradients and the drop shadow.
Perhaps the grey is a bit dark, and the text logo is a bit to plain - but the focus must be to find a nice symbol first.
Another thing - I need the symbol to work with borth the text logo "shifters" as well as the Swedish translation "Omskiftare". That means that when the winner is selected, I would need to versions of the text (not now). So using, for example, an "S" in the symbol would not work - better to make it abstract with no connection with the text.
And I like the thought of the abstract symbol to somehow relect a shift, a change. I do not mind some connection or relation with sci-fi or something like that - like a shape shifter, magic or just some creative force.
