Yeah, sure, you´d need a program for that, I mean "paint" would work, too, but I think it´s not very good! "Photoshop" would be the best I think! But I use "photo filtre", that is also quite good!
And then you should just try a few things like cutting pics and putting them together etc.! Use effects and just have fun with it! Do it again and again! You´ll get better and better and...trust me you won´t ever want to stop doing this!
oh, I almost forgot...I just made a new one! What do you think?
