Martin_Ocejo: Heh, I like how you say "you'll want to really define those round loops a lot more for a better profile", yet in your example image you have 4 whole edge loops (the mid-sections around the 2 central bump outs) which don't change the profile at all - they're essentially flat!
Agreed with what everyone else said, it doesn't resemble the concept at all. You should be trying an approach similar to this: That's just a quick example, but you'll want to really define those round loops a lot more for a better profile, at least that's my opinion. Hope it helps.
