Hey Erja,
Thanks for submitting another assignment!
Which lens are you using with your EOS 500?
Regarding focus.
You should learn the difference between your focus modes. Namely: One Shot, AI Focus and AI Servo
I can explain them quickly here. One shot means the camera will autofocus on whatever you’re pointing it at when you press the shutter release half down or all the way down. It’s good for stationary objects. AI Focus is basically for objects that are stationary but could move. Like a bird sitting in a tree that is about to take off. Now once the bird has taken off and is in full motion that’s when AI servo works best.
In AI servo mode your camera will continue focusing constantly until the shutter release is depressed. It’s great for say a big muscle man walking toward your camera!
Speaking of big muscle guys…
You have submitted three photographs. Let’s get right to it.
Your first photo features a big man walking toward your camera. You’ve achieved shallow depth of field here and the photograph itself is interesting so job well done!
The photo is slightly out of focus but now that you know AI Servo would be ideal for this situation you’ll get better shots next time right?!
Now for your motion photograph.
I suspect you we’re trying to achieve something like this:

Hard green shell by SergioTudela, on Flickr
Check out how this photo was taken:
Camera: Nikon D80
Lense: Tokina AT-X 12-24 f/4 AF PRO DX
Exposure: 1/8
Aperture: f/8
Focal length: 12 mm
ISO speed: 100
Filter: B+W F-PRO UV + Cokin Z121S
Tripod: Manfrotto 190XPROB + Manfrotto 486RC2
Note the aperture and exposure(shutter).
You need a tripod to shoot photos like this.
Otherwise if you were not trying to achieve that look than your photo doesn’t really show motion. It shows a frozen image of water. I can imagine that the water is moving but I don’t really see it in the photo.
I hope you understand what I mean.
Your last photo certainly depicts motion but the photo itself is not very interesting. A better option for this photo would be standing on the ground and panning as the scooter goes by. Like this:

You’ve shown that you can achieve both shallow depth of field and motion in your photos but you need more practice here.
I hope my examples we’re helpful.
See you on the next assignment!
