Hi Hayleyscomet,
Hows it going with PS4 ? It is a very daunting programme but can be learnt fairly quickly with the right books. I have been using PS 2 and PS 4 for a number of years now (just a hobby) and have found that the best tutorial books are by a guy called Scott Kelby. They are available in S.A but are hellish expensive. I have a few of his books and am happy to lend them to you if it will help you. Also a great site to go to is Worth 1000....here you will find the masters of the art and great competitions and tutorials. I enter a number of the competitions to improve my skills and get some terrific feed back from the real pro's on how to improve.
Another very good site is Photoshop Cafe, some excellent tutorials which are easy to follow.
PM me if you want to borrow the Kelby books and if you need any help with PS just shout..
The attached pic is one of my first attempts ....my wife has never ridden a bike ever ....pic is totally fake.
