Birch Wood

I have wanted to do something like this for a while. I visualized the birch forest with just white birch trunks. However after deploying the first version I couldn't make it look as I wanted, the trunks where just too tall (attached image) when in portrait mode (which must be the most common mode by far). So I started looking for a nice clean birch crown to add to the top of the trunks. After hours of searching both on Flickr creative commons and stock photo sites I couldn't find anything that looked nice. I added some green leaves but am not quite happy with the result. Better than the first release but I have to keep looking. Or bring my camera for a birch-hunt.
