Hey Kargaburun,
first of all, thank you for the purchase!
WordPress themes tend to look rather dull right after installation, because the default WordPress settings are often not sufficient for more complex themes, and thus certain theme settings need to be adjusted. The demos (including Tokyo demo) display a theme in its full potential, i.e. with some theme settings already tweaked.
In any case, I will gladly help you configure Tokyo; in order for the process to be as efficient and fast as possible, please provide the URL of your website, as well as a numbered list of things you don’t know how to adjust (the more detailed you get, the better it is, and the less additional questions I’m going to ask). I would also recommend to study the theme manual carefully before you compile the list, as it contains the explanations on the most important theme features and might solve some of your questions right away :)
Sincerely,
Andrii / Satori Studio
