The joys of lightpainting!
Some really good efforts there, I would say watch out for the hotspots its one of those things that still gets me when im shooting these type of shots. Its all trial and error to get a nice flat clean 'lit' surface
how far away was the light source? The trick is playing with different shutter speeds ive found, I think most of the time I would use something like 1/160 which helps cut the hotspots down. The only other cc i can really give is watch out for the shadows with the front end shot there is alot of shadow on the floor could use a couple more shots to light the floor at the front
But keep it up looks like your getting the hang of it
