I enjoyed the slice of the VN that you have in the demo! There's some very confident and effective use of varied typesetting here, and the whole has such coherent presentation. The committed choice of just a few colours works very nicely. I can't comment on the Spanish text, but I thought the English read well, with a good grip on register and dialect and some well-chosen idioms. (I think there was one line where I might have found toast more natural than toasts, but if that is the level of detail one has to zoom in to to try to give feedback, things are going well!)
If you do take this project forward in future, I'll be interested to see where it goes.
