It takes practice. =) If you really wanna get involved with making stuff, look for a more advanced image program. There are a whole bunch of free ones online =D I'd advise Paint.NET, cause that's what I use (and am in love with) but the learning curve is a bit steep. Either way, I got through it. If you do decide to go that way, I'd be sure to help you if you ever had any problems with it. =) If not, Microsoft Paint is always an alternative~
