Have to agree with the others I think the shutter speed is just perfect - I like the hand movement(blur). I think it is a brilliant first attempt and I agree with Michelle about depth of field issues and aperture - try shooting on aperture priority, so setting your depth of field, let shutter speed sort itself out, adjusting ISO if necessary.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
