When you joined DA, you were supposed to read the terms and services. If you had done that, you would have discovered that you aren't allowed to post art that isn't 100% made by yourself (unless, of course, it is stock art). Please remove the Miku Append from your gallery and do not post any more stolen art.
If you want to photoshop and have no talent in anything else, please search 'stock' on DA. If in the artist's description it says 'stock free to use' that means you can use it as long as you aren't using it for profit. You can combine different stocks together or pair it with something you made yourself, but you can't pair the stock with art that doesn't say 'free use'.
