Maybe you can help me to learn painting and drawing. 
this is my first pic. A short scetch … about 1 houre…
D thing is that my stuff looks like a child drew it…
Can you give me some tipps?
Did you use reference? If not, then make sure you do gather the references you need, because you absolutely do need proper references if you want to do any kind of artwork that isn’t extremely simplified cartoon.
One hour is a very short amount of time, so don’t be too hard on yourself. It doesn’t look too bad. I personally wouldn’t stack the main peak with the figure in a straight vertical line like that. I would place the main peak a bit more on the right side (to offset the slope in the foreground on the left) and move the lower peak to the left side, so they form more of a triangle with the figure.
