I am newbie in making beautiful, "complex" latex covers and I need your help.
I have the following very simple cover page but I will really like to make it look (as a structure) like this nice structure. I have seen this question which is a very good start for me to explore different styles I want something similar to the example.

does anyone knows a similar template?

RequirePackage{filecontents}

documentclass[12pt,a4paper]{article}

usepackage{titling}

usepackage[utf8]{inputenc}

usepackage{tcolorbox}

usepackage{graphicx}

usepackage{lipsum}

usepackage{mwe}

usepackage{subfig}

usepackage{float}

usepackage{authblk}

usepackage{afterpage}

usepackage[T1]{fontenc}

usepackage{booktabs}

usepackage{fancyhdr}

usepackage{array}

usepackage{pdflscape}

usepackage{array,ragged2e,booktabs}

usepackage{tikz}

usepackage{capt-of}

        protectfootnotetext{#1}}}

renewcommandtabularxcolumn[1]{m{#1}}



newcolumntype{C}{>{$displaystyle}c<{$}}

This should get you started.

usepackage{tikz}

usetikzlibrary{positioning}

usepackage{titling}



makeatletter

  gdef@subtitle{#1}}

newcommand{@subtitle}{}



renewcommand{maketitlehooka}{%

  begin{tikzpicture}[remember picture, overlay, outer sep=0pt, inner sep=0pt]

    node (image) [anchor=north] at (current page.north)

      {includegraphics[width=paperwidth,height=0.9paperheight]{%

         example-image.jpg}};

    fill [blue!60!black, opacity=0.7] (current page.north west) rectangle

      ([yshift=-0.3paperheight]current page.north east)

      node (title) [text=white, opacity=1.0, text width=17cm, align=flush center,

        font=sffamilyHugebfseries] at (current path bounding box.center)
