كيف أرسًم شجرة عيد ميلاد علىLaTeX باستعمال TiKZ؟

عندي لك اقتراحين اثنين لتعويض الشجرة:

الأول:

\documentclass[11pt]{scrartcl} 
\usepackage[dvipsnames,svgnames]{xcolor}  
\usepackage{tikz}
\usetikzlibrary{shapes,decorations.shapes}
\newsavebox{\mycandle}
\savebox{\mycandle}{ 
\begin{tikzpicture}[scale=.1]
\shade[top color=yellow,bottom color=red] (0,0) .. controls (1,.2) and (1,.5) .. (0,2) .. controls (-1,.5)  and  (-1,.2) .. (0,0);
\fill[yellow!90!black] (.8,0) rectangle (-.8,-5); 
\end{tikzpicture} } 

\tikzset{
  paint/.style={draw=#1!50!black, fill=#1!50},
  my star/.style={decorate,decoration={shape backgrounds,shape=star},
                  star points=#1}
}  

\begin{document}
\begin{tikzpicture} 
   \draw[fill=Maroon,ultra thick] 
   (.75,-1)  ..  controls (.5,.5)  and   (.5,3)    .. (0.5,4) 
-- (-0.5,4)  ..  controls (-.5,3) and (-.5,.5)     .. (-.75,-1) ;
\draw[ultra thick,fill=green!50!black] 
      (0,10) .. controls  (0,8)     and   (1,7)    .. (1.5,7) 
             ..  controls (1,7)     and   (1,7)    .. (0.5,7.25) 
             ..  controls (1.5,5)   and   (2.5,4)  .. (3,4)
             ..  controls (2,4)     and   (1.25,4) .. (1,4.5)
             ..  controls (2,2)     and   (3.5,2)  .. (4,2)
             ..  controls (1,1)     and   (-1,1)   .. (-4,2) 
             ..  controls (-3.5,2)  and   (-2,2)   .. (-1,4.5)
             ..  controls (-1.25,4) and   (-2,4)   .. (-3,4) 
             ..  controls (-2.5,4)  and   (-1.5,5) .. (-0.5,7.25) 
             ..  controls  (-1,7)   and   (-1,7)   .. (-1.5,7)
             ..  controls  (-1,7)   and   (0,8)    .. (0,10)
              ;
\foreach \candle in {(2,5),(-2,5),(0.5,7.5),(-0.5,7.5),(-3,2.5), (3,2.5),
                    (1.5,1.75),(-1.5,1.75)}
\node at \candle {\usebox{\mycandle}} ; 
 \node [star, star point height=.5cm, minimum size=.5cm, draw,fill=yellow,thick]
       at (0,10) {};
       \begin{scope}[decoration={shape sep=.2cm, shape size=.25cm}] 
    \draw [my star=6, paint=red]  (-4,2)
             ..  controls (0,2)     and   (1,3.5)   .. (1,4.5)
             ..  controls (1,6)     and   (0.5,6)      .. (0.5,7.25); 
    \draw [my star=6, paint=blue]  (4,2)
             ..  controls  (0,2) and (-1,3.5)      .. (-1,4.5)             
             ..  controls (-1,6)     and   (-0.5,6)      .. (-0.5,7.25);    
       \end{scope}  
\end{tikzpicture}

\end{document} 

لتكون نتيجة الشجرة كما توضح الصورة التالية:

ثم الإقتراح الثاني، هي نفس الشجرة، لكن بتأثيرات أخرى مغايرة للأولى، كاضافة بعض الكرات والثلوج:
