Love this….GO BUMBLEBEE!!!!
Think this is a fresh take on the overplayed skull theme.
Its difficult being original when it comes to skulls these days.
I hear what Simon is saying though, maybe diff kind of shading element is needed in the bottom half of the inner circle.

I think it’s time we introduced a “no skulls” clause to the rules…

NOT becuase I have anything against your design – I really don’t – but because the skull is becoming the new bird on a wire, and it cannot get that way.

I Like your choice of orange against the grey metal helmet piece, but I think the design is too busy, too detailed, in a sense that when I look at the shirt, my eyes jump everywhere trying to make sense of it.

Transformers fanse? Be careful when targeting such a niche market, because you’re omitting the 70% of non transformers fans’s from your votes.

You have a clear skill and ability, I would love to see you apply it to something a little more out there.

first i thought it was a cycling helmet, then i thought robocop? cool design for those out there who aren’t tired of skulls as a motif yet.
