Initial impression: Fun to look at and does definitely look like it was taken while on a swing.
Technical: A few hot streaks in the light blurs, composition a little scattered, found my eye roving a bit more than I'd like....but then you were in motion! Not so sure if the tilted angle went over as well, here people seem to like their horizons level. Long exposures always mean a more interesting shot. Wonder what you would have got with the shutter stopped down a little and a 1-second exposure?
Artistic: Like that you can see the texture of the bark on the trees. That and possibly a bit more saturation to help the colours pop more.
Overall: An interesting shot bordering on abstract and definitely the work all Team Suckers should aspire to! Good work! :-)
