If you only want constructive criticism I suggest you show your mum.
All criticism is helpful to the open minded and wise.
Asking for only constructive criticism is tantamount to only asking for praise.
Sorry but I am bored of people asking for constructive criticism and generally ignore threads started like that cos those are the people who are likely to throw a paddy when we dont all go ' ooooooo arent you clever'
But dont despair most regulars are nicer than me.
It would be nice if more people gave as well as took in this section... I make a general observation there - not directed at you.
