Marvel doesn't like splash pages since they don't tell a story...Marvel wants 5 pages or so of sequential art,not pin ups,splash pages ect...Let me break this down a little bit for you...
Page 1.....Use boarders,Jim Lee gets away without using boarders since he's the richest guy in comics.
Page 2 1/2 splash,I'm not really getting a clear picture of where the Hulk is, Just because you know where he is, doesn't mean the reader knows,Panel close up on Hulk's face is nice but ears are off anatomy wise.
Page 3....Again a Splash Marvel doesn't wanna see.
Page 4....In the 1st panel he's looking at the villain face to face,then in the (again the 1/2 splash) he's looking up at him (fix hulk's right hand) Then he's jumping up at him.
Page 5 (grr..another 1/2 splash) Panels 2,3 and 4 read from left to right...Last time I checked,people have been reading comics from right to left,you have it going in the opposite direction. (again use boarders) Panels 5-8 aren't smooth flowing and the camera angles are horrible.
On the positive side, I like your style and think you have potential,Just work on your storytelling and your anatomy a bit.
