Gilad Mass has more nature, abstracts, and macro photos at his site. Lovely work! 
Had to share one more from Gilad Mass. Quite a diverse portfolio. 
Nauset Galactic by Timothy Little at  Love the composition of our light (from the lighthouse) adding to the Universe’s light. 🙂 He also has a diverse portfolio, so go take a look.
