Very imagery-centered, which was just plain pretty in this context, though I would warn you against writing a piece this image-centered that was any longer than this in the future; the length works really well for what's here.
Main adjustments I would make would be to the dialogue; I have no idea who's talking at any point, the things that they're saying don't sound like things that people actually say that much:
“It is true."
This second character is basically using a vocal filler at this point to remind the other person that they're still in the room, so "Yeah" or "Tell me about it" or something similar would make more sense.
“I mean this is exciting! This might actually be cool, you know. Like this is really original.”
First of all, if this is AWCY, I'm immediately looking askance at any use of the word "cool" that isn't ironic or especially meaningful. You also need commas after "mean" and "like".
“I like how you did it though. Pens and paper, all old school. I thought you would be typing it down from the start.”
"it, though", "old-school".
“…”
If I were writing dialogue, each of these lines of dialogue would have either dialogue tags ("I like how you did it, though," Gustav said) or would indicate the speaker through action (Gustav was practically bouncing off the walls. "This is actually working!" etc.) If you do it like that, whichever speaker is doing the "…" should be doing something more like "Gustav was silent" or "Gustav paused for a moment" or something like that. Again, you /can/ leave the dialogue like you have it for stylistic preference, but it's gonna catch some readers as odd as is.
Other than that, good to go.
