I like the costume. Yeah, though open to the GotG costume, I'm glad to see Hercules sporting something more in line with classical looks.
As for the story itself, it looks good, but I'm still waiting to be sold on it. Sometimes I like random groups of characters who use the term Avengers, and other times it falls flat. (Let's just say Captain America, Mr. Fantastic, The Invisible Woman, and the Forgotten One weren't exactly a sterling example of Earth's Mightiest Heroes for me). Part of me wishes there was a 5th member here. Still, the story looks promising.
