Just learn to film how you skate.
If you skate unrealistic film unrealistic. If you skate realistic film realistic.
I happen to skate both ways.
Started a tutorials thread, link in my signature. Maybe it will help, if not post up.
Tell me what you need to know and I'll get to it later today.
Keep at it, It comes in time.
The only thing I would say work on and I haven't even looked at your footage yet
Angles.
Angles are everything if you ask me, just don't film to far off
Find that perfect angle, bam!
