Cliched, but often true.
I like everything in today's strip (The Bonnie Situation - Part Three) except the first panel, which is crowded by the art and the script.
First: the art. As a commenter commented, and as I've commented before, the vertical line denoting the corner Cole is coming around muddies things a little. At first glance it seems like it could be a gutter. Some very simple shading could solve this, or you could even do without the wall altogether:
Have Brent standing behind Cole and give him the first line, then have Cole react.
This has the added benefit of having Cole react to an in-strip event, rather than having him turn the corner and run into Brent in what we could call panel 0, an un-illustrated event that we have to assume has taken place. I'm not saying that "panel 0" events are a bad practice, I'm just saying it's not ideal, and we could have gotten around it here.
(There's probably a name for "panel 0" that I don't know about. Anyone? "Closure" doesn't seem to fit.)
Second: the script. Cole's line, "GAH! Jeez! You scared me," would have been just as effective were it just "GAH!" I suspect 99.9% of the readership would have understood immediately, the rest would have picked up the context from Cole's expression.
