Meg and I had a little jaunt over to Melbourne a few weeks ago, she for work and me just because.
I spent the better part of three days working on my street technique and discovered a few things.
1) your mistakes are often your best stuff, even after all these years. Frustrating but true. Maybe it's that you are as surprised and delighted as another viewer by the discovery of a new image taken "less well" that works or maybe it is just luck.

2) Technique that works in one city may not work in another. Harajuku Japan suited the 17mm focussed on about 2 mtrs at f4-5.6. Melbourne defied this. Maybe the distances were different, or the people or the light or maybe my mojo was not packed in the case when we came over, but for some reason a longer (25/45mm) lens was more successful, even for grab shots.

3) Revisiting the same place gives you a feeling of easy comfort, but this may not always be a good thing. Seeing differently is not always linked to just seeing different things, so reinventing yourself in a known haunt is tough, but clearly defined and going somewhere new is not automatically going to change you, just your view. Be aware of the difference between improvement and being in a rut.

4) Those little OMD cameras (and Pens) frikkin' rock, even the old ones! The lenses aren't bad either. Yeah they miss the odd shot, as do most cameras, but if you are prepared and "sorted" with your technique, they are quiet responsive and deliver a deep and glowaciuos image. This is only getting better in the newer models, but any of the cameras with the 16mp sensor or later are good.
