The lightning and composition are really good, and it seems like you have mastered the technique behind timing the photograph with the splatter. To add interest and uniqueness, I only suggest that you experiment with adding some color to the water. You can use food coloring, flash gels, or simply a colorful background to create nice reflections. Also, try mixing different substances, like water and oil, milk, or colored cream... the possibilities are endless. You are on the right track, great job!
