It’s a bit hard to follow the last bit with the spanish, but I assume it’s saying not to drink the pills? It’s a pretty cute concept!
One thing I’d say to look out for is placing your word balloons over important parts of the panel. Trying to avoid placing balloons over characters, especially their faces. Anything you want a reader so see shouldn’t be partially behind a balloon (unless that is meant to convey something, like being talked over, or maybe being hurt by someone’s words.)
