Pepe, I like the texture of the shape, it is very well done. And the shape of the header and footer parts are nice.
However, I can not like that Manta and where the character picture is put in. Also, the borders are too soft and too thick... Also, Logo could be placed at a place like where the Manta is, maybe taking a smaller space.
Something close to Pepe's texturing, metal at parts, almost like a blade's surface along with techy, I think that would fit the BHG the most.
If people happen to create something extraordinary, I can increase the payment up to 500,000,000 SC. But really it depends on your work, and me liking it that much.
