\usepackage{tikz}
\usetikzlibrary{positioning}% To get more advances positioning options
\usetikzlibrary{arrows}% To get more arrow heads

which produces
I would like the green arrows to be pointing to itself. I therefore tried to modify the line
\path[->, MyColor1] ($(\x)+(0,0.3)$) edge [loop above, out=120, in=60, looseness=8] node {$h$} ($(\x)+(0.5,0.3)$);
to
\path[->, MyColor1] ($(\x)+(0,0.3)$) edge [loop above, out=120, in=60, looseness=8] node {$h$} ($(\x)+(0,0.3)$);
following the answer of this question, but this results in only the arrow heads being drawn in place. I also tried the following
\path[->, MyColor1] ($(\x)+(-0.025,0.3)$) edge [loop above, out=120, in=60, looseness=8] node {$h$} ($(\x)+(0.025,0.3)$);
(baisically shifting the center to the label and then just making the gap between beginning and end smaller), but this resulted in a very small arrow... Can somebody maybe help a bit?
PS: I'm aware of the fact that I'm doing something wrong by constantly manipulating coordinates to specify beginning and end of arrows, etc. but I just don't really know how to do it otherwise.. If someone wants to suggest a solution for that as well, then it's obviously very appreciated!
