To answer the OP -- apart from what's already been mentioned, remember that each scene has to exist for itself. That is, it isn't something to rush through to get to the next exciting thing.
For each scene, think about where it is (describe physical setting, including smell), what happens (what events take place), how your characters are feeling (narration, emotion), and what's the conflict. Take each scene as it's own mini-story with beginning, middle, and end; goal, motivation, and conflict.
If the scene seems rushed, go back and flesh it out. Are your characters interacting with their environment? Are they talking to each other? Are they expressing (internally, depending on POV) how they feel about what's going on? What is the goal they're working toward, how are they being thwarted, and how are they acting to overcome it?
TL;DR - the scene isn't there as a way to get to the next bit. It has to stand on its own as well.

Sorry, rambly. Not sure if that helps at all.
As always, it makes sense in my head!
