"Again a few bad photos"
There is nothing wrong with your pictures. Actually, they are very good. They are much better than my photos. You have a much better equipment for photography than me.
"I have a Nikon B500 Bridge, which has 40x optical zoom. I like it, because I can shoot a lot of things which are far away."
Wow! That camera costs more than my current monthly income in real life. So the price of the camera is also shoot far away. Like the starry sky.
My current photo equipment is currently consist of a smartphone (Huawei Ascend Y300) and a classic phone (Nokia C2-01). Nothing Bridge, DSLR or other expensive cameras.
