My honest opinion Chris is that i am not excited by the pic, however i really like the way you have captured the setting sun through the windows of the ferry terminal. It also has a really intriguing two-tone sky. I think perhaps some more aggressive cropping could have pinpointed the focus of the subject.
What you could do is think about 'what is the subject?' Is it the ferry terminal or is it the setting sun through the glass? Although i like the reflection of the sun in the gutter on the left, i feel that it could be excluded from the whole shot and make a closer crop of the part of the terminal where the sun comes through on the right-hand side of the frame.
Just my own thoughts out loud so don't take any notice of me
Please, please, please, keep experimenting with light. Light will make or break a great photograph so the more you experiment with the D70, the more you will learn it's foibles and characteristics and how it handles different types and angles of light.
Oh, and thanks for sharing with us. I do enjoy looking at your photos.
