One of the most challenging aspects of taking an image like this, be it at sunrise or sunset, is being able to balance detail/exposure in the foreground and background because of the potentially great differences in EV's. One of the best ways to handle this is to use a graduated neutral density filter. Set your exposure for the foreground and let the ND filter reduce the EV's in the background so they are more even. I have one which is large enough to use with my Hasselblad lenses, some of which have a 90mm filter thread, but I have step down adapter rings so the filter holder can also be used with my Nikkors. The nice thing about getting a rectangular one like that is you can adjust it so its position matches the composition of the image.
I am glad to see, however, that you did not place the horizon halfway in the frame, an all-to-common mistake, but adhered much closer to the rule of thirds! The composition is very good.
