So far I'm digging the one shot, your action poses are definitely top notch especially when the dream sequences come to play. I'd love to see more action when the time is right especially when Dream Boy goes against the big bads!
However, I think the pacing is a little off putting, I had to take moments to reread the pages again to really make sure what I was reading was correct. You're going wayy too fast in the action, and while that is nice, it's best if you give your audience some set up before you can really throw us into the action.
Another problem is your comic bubbles, the text is way too cluttered, and there was a part in the comic I couldn't read properly since the colors were extremely bright against a grey background in the comic bubbles. You don't need to use massive bubbles to cover up actions, instead you can give the characters gestures instead of rushing the dialogue.
While dialogue is difficult to do as well as conversations between characters, in character dialogue can definitely help more with world building. :>
