你翻译的已经很好，最后两句似乎可以稍微简化一下：

My friend says goodbye; departs to Yangzhou, west of the Yellow Crane Tower,

In the March, fluttering catkins all over the sky and blooming flowers.

His lone boat moving further and further and disappearing in the blue horizon,

Only the Yangtze River flowing into the sky.
