You've clearly and simply depicted the types of style that can be created with Photoshop. It's organised and all of the styles are different and displayed suitably large enough for any budding artist to copy.
This idea has been used before, but you have shown styles that I haven't viewed or seen before. The layout is nice simple, also all styles are unique and all different. You also have a large range of styles that are available for choice.
I cannot fault you on the way you've drafted the styles because they all clearly show the supposed metal. The text and such is large and you have enough examples of different words to show versatility.
