Basically, what illustrator is, is a much more sophisticated version of ROME. You are able to do many more things on it. It is a program that many professionals use for their work, and it is incredible all that they are able to do on it. It is also vector based.

Unfortunately, I am not very confident with illustrator. It is very different from ROME, and has so many more features. Its really difficult working will all of them, since with illustrator you have an opportunity to adjust EVERYTHING and be very particular. It just makes things more difficult for me. I have to make so many adjustments and it usually ends up ruining all my projects, even though I have done the tutorials.
