There are many shops in it. You should find a PS shop with more replies. Generally speaking, non-mainstream is not good. We hate non-mainstream. You can take pictures of scenery, animation, original pictures of Europe and America, and put a QM but, which means signature, and others will do it for you.
PS is hard to say. You can't find the material, so you haven't learned it, and you can't do it all at once. PS is difficult to learn, but mito is easy to destroy. You'd better go to another store to place an order before you learn it.
I suggest you go to PS tutorial to learn the basic tutorial, Baidu search also has it.
I hope this helps.
