Lovely Entries this time again. I think we are gettung better and better. I try to say to every pic some things, as I liked it when others have done that on the competitions before. Please see all critics as constructive:

#1 Maemish
Nice pic and fitting well to the May topic. The old instrument is well balanced in light and shadow. The screen (showing you?) is for me somewhat irritating. On one hand it's a nice contrast, on the other, it's somewhat disturbing.
9/10

#2 DDark
Also a good shot. Anyway for me it doesn't fit so well to the topic. If the topic would have been pattern, I would have given you full points. All these lines are really fascinating and are drawing the viewer into the pic. (Minor thing: I would have cropped the pic a little bit at the bottom)

Even though that you can very well see the limitation of smartphone cameras in darker settings (Details are missing completely), i'm still impressed how you and the N900 camera mastered this situation. The pic in whole just works and the topic is hit 100%.
9/10

A setting that for me only work with heavy post processing. The dark areas especially at the bottom are to dark. Without tone mapping you can't manage that high contrasts of this scenery.
6/10

#5 Pentona
Like the last time a pic that enfolds it's real beauty only in larger size. Nearly a perfect picture, nearly the matchwinner for me. But I think you should have cropped more at left and top to make it perfect. And of course there is the next entry...
10/10

#6 Pichlo
All said about this one. The play of light and shadow, the abstract motive, the depth...
Real art
10/10 - And my WINNER of the May competition
Edit: The last pic of you is horrible. But looking at the shadow of the cable... unbeatable. Maybe you would have won with that one, just because you simply smashed the May topic.

Nice "kangaroo" in nice light. It must have been quite near. Unfortunately the cam of your OnePlus One seems to be worse than the Jolla 1 cam. The noise reduction killed the gras and made a carpet out of it. I would have cropped the pic a little bit more but that would have made the noise reduction even more present.
7/10

#9 rm250j
Dramatic scenery. Anyway this pic seems to me more a snapshot than a carefully taken photo . Maybe you should have changed the position a bit.

#10 catbus
That's not your car!
Nice Idea fitting well to the topic. But the only thing which I can really identity is the bulb. Anyway the pic works somehow.
8/10

#11 Macros
Lights and Shadows, The pond mirroring the sky. The May theme is hit by 100% but my eye doesn't find a real rest on your pic. There is no point where the view is drawn.
7/10

#12 spfoo
Your pic looks on the first glimpse like a copy of catbus' pic. But yours is real art.
BUT: This is not R2D2
10/10

#13 mosen
You nearly got me: BEER!
But than I realized. the foam doesn't really looks like beer and the colour is quite bright. That must be something different. Is it a Radler?
Good picture, But the May topic for me is not obvious, even if there is a lot light and shadows.
