Romantic development - comments please!

Someone on www.goodreads.com wrote;"FOR THE LAST TIMEAUTHORS, making your two main characters feel "unexplainablyattracted" to each other does NOT make up for lack of proper romanticdevelopment."
Am I achieving proper romantic development in the following excerpt from my novel, a work in progress? 


 It is 1869.


Jakob Kleinnoerdlinger has just spent 4 days crossing the Karoo, the desert in the heart of South Africa. He has reached the town of Graaff Reinet where he has just met Mr Frederiks, a timber dealer, with whom he plans to do business. This excerpt begins just after Jakob has been shown around the timber yard.
