I know you said you weren't a fan, but drawing from life is the best way, in my honest opinion.
This pose looks stiff and unnatural, because you are trying to draw it from imagination. Now, I'm not saying drawing from imagination is a bad thing, but it's not easy either - especially for a beginner. That's why Pictionary is so funny. 
I recommend collecting up some references that you do like. It'll give your creative brain more material to work from.
I had a quick google search and found some lovely poses. I think with an embrace, it's important to show the hands (which are hidden in your example). How they are physically holding one another will express so much more information. Gentle hold vs a lusty grab for example. Maybe push their foreheads together?
I hope that made some sense. I am certainly not a qualified teacher.
