Ready for another tip?
If there's one thing that's a staple of superhero comics, that's the fight scene. There may be one or more in a single comic, but generally, you should understand that the fights are very much like a dance. Know what dancers need?
Now, I know that some of you are in love with the sound of your own voice, and on top of that, you want to show off whatever knowledge you have gained about things. You want to speak in specifics to show that you're “with it.”
Remember that the script is only going to be seen by no more than five other people. More if you show it to friends in order to get their take (or if you submit it to The Proving Grounds). If your character is a martial artist and you start going into the Japanese or Chinese names of stances and strikes and blocks in order to tell the artist what to draw, then unless your artist is also a martial artist in the same system, then they're going to come back and ask you what the hell you're talking about. (And yes, I've seen these scripts.)
If you're not good with choreography, do yourself a favor and leave it up to the artist. Tell them what you want and how the fight is supposed to end, then sit back and let them do their thing. Let them worry about the pacing. You're going to have to worry about what the characters are saying as they brawl.
If you're good with choreography, then by all means, go for it. Thinking up fights can be fun, and it can push you into looking at things, or having characters use their powers in innovative ways. You could be adding to the canon of a character. (I happen to love Iceman, and would do all kinds of crazy things with his powers. He'd be extremely hard to beat under my direction.)
Choreography can be good or bad. Like everything else, it needs to be practiced.
