It’s a compliment. However, if that is the only compliment he has given you, he is not entirely sure about the rest of your personality or whether there is more to you. He probably wants to see more, if more exists.
If there is more to your personality, show him. Show him that funny or adventurous side of you. Whatever it is, start making it a point to let him see other facets of your personality.
This is what he needs in order for him to start looking at you as more than just an intelligent girl.
This is when he is most likely going to start looking for traits that he has in common with you. The more he finds that he has in common with you, the more he entertains the idea of whether the both of you are a romantic match.
