#2 is definitely the most interesting one (I find the subject pretty cool), even though my eyes gets completely lost in it. Nothing
pops, there is no
anchor, no leading lines.
Also, about the watermarks. Well, it is a completely different topic (and there some good threads here on PF about it), but in my opinion, you really can never be safe regarding your photos. Certain type of people will always find ways to steal no matter how hard you will try to protect your work. So, why even bother? Look at it from a different perspective,
if someone steals your photos, that means they have value. Looks like even kind of a compliment, m?
