i did this just recently while i was actually on holidays in a beach town (agnes waters in central queensland, australia in case anyone was wondering). my gf and i watched a few sunsets together which inspired me to do this.
i don't do much post-render work either...i'm aiming at getting into the gaming scene, so its kinda outa the question in my books
i would also welcome any tips from ppl too
keep up the good work
