do teh floppy, it takes 2 mins, a black square with some stuff inside to differenciate (cant spell) between floppy 5 and 3. those are the easy ones...hahha my icons can take up to 3 hours just to make one, but i put alot of detail into mine.... I have some suggestions for you though,
that folder with the cd icon, make the cd larger, dont forget that people see these from a small resolution most of the time, so they have to be able to visually conect with the icon on eye contact. it sounds stupid, but its what we all do.
I would also make the torch burner icon and the square icon thingy beside it larger too, and the cd with the cross on it larger too, the folder sizes are perfect.
one thing though..... in folder icons you have two folders one is called "front" and the other is called "back" these two folders, windows 7 and vista uses to make up their own folders. you have to make sure they are aligned and in the correct position so when they are used to make up a folder, no pictures, documents ect are sticking out the back of it.
the best way to see how your folders are working is make a new icon package, and just import those two folders then apply go to my pictures or something and see how they are working and then adjust till they are spot on.
I did this with techno mi icons 5 times till i got it right, but now i have the template for it, so i wont have to do that again !!
it dosent matter how long it takes to make them, they will get finished eventually......
