Back side 180

Nice series.
I've been skate boarding since 1976 and I still don't know how you guys keep the board stuck to your feet in mid air, let alone landing the wrong way round and staying on. Even in those days I gave up the tricks, attached my wheels to a 4 foot (sorry, 1200mm) builder's board and raced my friends on their mopeds. I now have a 'proper' long board...
Anyway.. if you want that series or a single frame to have a bit more oomph try getting in low and real close.
Choose a wide angle
set your camera to aperture priority
set it to a high f number like f8 or f11 - this will mean you don't have to focus so turn off autofocus and just guess. The shutter speed will be low, helping to emphasise the movement. You can flip up the flash if you wish, but set it to slow sync to get some blur and stop the motion as well.
