Applying ICC profile and Anti-aliasing

I need enlightment on how to use the applying ICC profile and the anti-aliasing options. The little i know is that not applying the ICC profile and anti-aliasing will lighten the colour and distort the final work respectively but it seems its somehow diferent if mesh fill is used. I have an attachment that it seems it is nt clear enough compared to my previous works and i will like you to rate my work cos i'm a newbie, i read Ariel's tut on x4 so i gave it a try. Thanks for your replies in advance. CorelDRAW X3
