How to draw a diver in TikZ?

Question

How to draw a diver being trained in a tall water tower in TikZ?

All what I have (been able to) do(ne):

\documentclass[tikz,margin=3mm]{standalone}
\usepackage{siunitx}
\usetikzlibrary{patterns}
\begin{document}
\begin{tikzpicture}
\draw (0,4.5)--(0,0)--(2,0)--(2,4.5);
\draw (0,0) rectangle (2,4);
\foreach \i in {0.2,0.6,...,3.9}
    \draw[ultra thin,cyan,dash pattern=on 4pt off 4pt] (0,\i)--(2,\i);
\foreach \i in {0.4,0.8,...,3.9}
    \draw[ultra thin,cyan,dash pattern=on 4pt off 4pt,dash phase=4pt] (0,\i)--(2,\i);
\draw (-1,0)--(3,0);
\fill[pattern=north east lines] (-1,0) rectangle (3,-.2);
% Do something with the diver at (1,1)
\begin{footnotesize}
\draw[very thin] (1.5,3)--(2.5,3.1) node[right,align=left] {
    sea water\\
    (density 1020 \si{kg.m^{-3}}\\
    or 1.02 \si{g.cm^{-3}})
};
\draw[very thin] (1,1)--(2.5,1.2) node[right] {diver};
\end{footnotesize}
\end{tikzpicture}
\end{document}

I can't draw the diver. I have seen many TikZ-drawn people on this site, but none of them is a diver.

Moreover, if I could draw the diver, I would also not able to clear the "water" blue dashes behind the diver.

Please help me. Thank you in advance.

I'm sorry but I can't provide the image in a better resolution and quality.

One can draw such things but as Uwe Ziegenhagen says it is a lot of efforts. (Doesn't take hours but certainly more than 10 minutes.) The main problem with such figures is that one is never really done, there is always something that you can tune more.

\documentclass[tikz,margin=3mm]{standalone}

\begin{tikzpicture}

\draw (0,4.5)--(0,0)--(2,0)--(2,4.5);
\draw (0,0) rectangle (2,4);
\foreach \i in {0.2,0.6,...,3.9}
    {\draw[ultra thin,cyan,dash pattern=on 4pt off 4pt] (0,\i)--(2,\i);}
\foreach \i in {0.4,0.8,...,3.9}
    {\draw[ultra thin,cyan,dash pattern=on 4pt off 4pt,dash phase=4pt]
    (0,\i)--(2,\i);}
\draw (-1,0)--(3,0);
\fill[pattern=north east lines] (-1,0) rectangle (3,-.2);
% Do something with the diver at (1,1)
\draw[very thin] (1.5,3)--(2.5,3.1) node[right,align=left,font=\footnotesize] {
    sea water\\
