Look, bro, you're trying your best, but you need to work more.
You are creating almost every widget with dark theme and old design which doesn't look good. For me I'll never add this widget in my blog firstly due to its design, secondly due to its font.
The design you're using was used in old days as nowadays material design and flat design is getting boost.
And I don't want you to get depressed by my comments but just suggesting you as I don't think 90% of your visitors will add it in their blogs. So what you can do is change the theme of box from dark to light, remove the orange background in headings, change buttons style.
Further, if you need any help,feel free to ask.
Hope you understand
