The paintings are not pre-determined events. If I recall, both Peter and Claire ran up the steps, there wasn't a point where it was just Claire so that painting did not take place (or hasn't yet anyway). Hiro should be visiting the school with his buddy to look at the banner, this might be upcoming once he returns from his journey.
There was a point where it was just Claire and Peter was following with his shadow on her. I assume the Hiro/Andro painting will still happen.The paintings have been accurate with perhaps a slight artistic exageration (size of shadows etc)

Greg Beeman's Blog gives some insight into this episode.
The paintings which Tim Sale creates for the show happen in two ways – sometimes we film the event first and give Tim the frame we want to match to. Remember when Hiro and Ando stood under the rocket ship in Tokyo and looked at the exact same frame in the comic book. Well, we'd filmed the Hiro/Ando shot first and did the comic panel as an insert later. That way is way easier for all concerned.
But… the paintings in Isaac's loft were a different story. Tim Kring and the writer's gave Tim the idea of what they wanted and Tim painted the paintings in a vacuum, before we ever had sets or clear ideas of how we'd end up shooting the scenes.
Now it was time to re-create most of the paintings in the episode. I took this task to heart, knowing that if we could recreate the paintings as closely as possible HEROES would look like a cool-### show that had been carefully planned from the very beginning. The first was the painting of Claire running up the stadium stairs – this one had already been done in episode 4 and my job was just to make sure we got back to the same angle and re-created the shot as closely as possible. The second was Sylar standing over Claire's (actually Jackie's) dead body. This one was really hard, because Tim had painted the image in an unnatural perspective with a HUGE Sylar standing over a tiny dead cheerleader. I tried my best. Put Sylar in the right position. Put the cheerleader in the right position. But couldn't match the shadow or the scale. Finally had to match Peter having lockers thrown at him by Sylar's force. At the time the writer's conceived of this one and Tim Sale painted it – no one had any idea how it would play out – just that it was a cool painting. I had to vamp the space this happened it, but in the end it's a pretty good match. The last painting, of Hiro and Ando standing under the bloody Homecoming banner was another challenge. When Mr. Sale painted it, no one had any idea that he was even going to make the banner bloody, much less how we'd accomplish it. This painting actually plays out in episode 11 – but we had to come up with a way to set it up in #9, which we did in the scene where Jackie gets murdered.
