Camera Lense Techniques-Motion Blur

For this brief we had to show different lense techniques shallow depth of field, drop focus, focal length and motion blur, I'm happy with some of my images a lot more than others i will explain as i go . . . . . . here are my images . . . . .

This is motion blur i thought it would be good to try something a bit harder and new for this as i have done traffic trails a few times before which is the obvious motion blur choice so tried to do something i haven't tried before, i think the first image is the best and that's why it is at the top i like how it shows movement but you can still see the fingers i tried a few times and only managed to get a pink blur where the hands should be but i think this works better where you can still make out the outline of the fingers i left some others in i wasn't completely happy with to show the different speeds.

I tried to use a long shutter speed with this tree i saw it blowing all over in the wind and thought it would make a god image but instantly didn't like the result i still put it on here to show my mistakes its good to learn from.
I also tried some motion blur images in my sink at home i wanted to create a sort of whirlpool effect i tried it both with just water and with soap and water as well so you could see the water better with a bit of colour in it however i wasn't able to get the effect i wanted so i tried something else and preferred the guitar images.
