Strong design elements artistically combined: color contrast between gold tones and blue combine with strong dark shapes of pier supports and dark horizontals of water ripples. Could consider cropping away the upper part of the distant pier where the white light and paler cyan tones dilute the impact of the main part of the image.
The bird detail, the cross, and the solar flare are nice details. The golden tide is excellent as well, and where this falls short, is the inclusion of purple. the blue and purple combination doesn't work so well.
