Hiya Kev,
Well what can I say ..... my words would be

..... my 6 year old son's comments were "Cool! that is a groovy moving photo .... mum when can we take a photo like that?"

He then went on to ask if this is the same friend who made the lego man movie? (kids and their memories .... if only I had his ability to remember things

)
I like the fact that you have taken it through the rear window .... as you say .... how many of us think of where we have come from ..... or where we are going to

what a juxtaposition that is
The music really adds to the vid, great track choice too. It's amazing how the dull, rainy weather on the way to work played in your favour regards exposure as you pointed out the +OE on the return trip is a tad bright .... but heyho that is how the weather seems to go .... and as this was your first attempt at such a technique I think you have done well and will learn from same.
You mention that it took 3630 frames to compose this video .... what a fluke it would have been if it had landed up being 3333 photos
I look forward to seeing more of this type of work from you.
Well done
Cheers
Dawn
