Something I find to be helpful is to be aware of your character's surroundings. In real life, you always seem to focus on one or two things in your surroundings. Well, you actually notice a lot, but putting too much in could make the reader bored.
Example: Your character is walking through the mall. You could say that they "drifted through the crowd." But maybe your character sees a few things that put more of a touch on it too. Like, maybe a woman is pushing her child in a stroller, and she can barely move without wondering who's feet she's about to run over. Or, your character sees a man at the fountain holding his child's hand, waiting for someone to move from the bench so he can sit as well.
I don't know if this is something you would do, but it's something I like to do, because it adds more focus to the character's surroundings, and also - like in the above example - it adds a showing effect rather than a "telling" effect.
