some key points:
• don't forget your grammar particles: li for predicates; e for direct objects.
• adjectives come after the noun (i.e. modifiers follow the head word). it looks like you had that correct with jan esun, but the same rule applies to soweli seme (which animal).
• for phrase "so many cute animals around!" you might consider more literal wording: soweli suwi mute li lon.
this is good practice. keep it up! 🙂
