General Design
Jumadi looks so mysterious and dangerous with the red and black tone, bold and daring layouts, big fonts, ... It's like you're watching a horror movie or joining an adventure. But I think because of this special style, Jumadi just matches certain kinds of users.
Other Elements
Color and Font
As mentioned, the red and black color dominant every element of this free multipurpose theme. If you want your site to have a brighter look, don't worry, you can change the black background with any color. But the red color is unchangeable so I'm afraid that this color scheme may not totally suit your taste.
Jumadi uses big and bold typography. The solid and strong fonts make it much more robust. You can also change the typography, but I think the default style is the best choice for the theme's spirit.
Page Layout
Besides the full-width default layout, Jumadi is flexible with changeable container width and styles. As for me, all styles look okay. I just find that the one container style and separate container style aren't so different!
Header and Footer Layout
The header layout is also flexible. I reviewed all the layout:
And think that the default style is still the best, especially, the left-hand title makes the layout more well-organized.
Similarly, you can choose the container or full-width layout for the footer. But it doesn't really important to me because both layouts are good. Just look at the footer column. Even when you choose up to 5 columns, it's still tidy.
Sidebar
Except for changing the sidebar position or hide it, you can't modify its style. I think that the author should add another style, which separates or distinguish the different widgets in the sidebar make it airier and readable.
Archive Pages and Single Post Pages
There is one style to display posts on archive pages. I love the large featured images, but I don't think displaying the category like this is a good idea.
Although these small icons are beautiful, the arrangement of this content leaves a lot of blank space, making each post look unsymmetrical.
Responsive Design
It's no doubt that this free multipurpose theme display beautifully and reasonably in all viewports. But I find that the header menu on mobile takes a lot of space. In my opinion, it should be smaller to be harmonious with other elements.
