Small essay about summer. Please and see if I have the any incorrect wrong sentences.

The Summer came. who told you? (What does this mean? You would just say Summer has come, or summer came. I don't understand what you mean by 'Who told you?') Oh, the original is rain. (I don't understand this part either. The original what?) Summer rain is light blue! When summer arrived, it began to drizzle, like such as silk or smoke, in the mist of the background. (which background?) It was very beautiful. In the reservoir, the water rose, fish swim swam in the water (You have already specificed that you are talking about water, you don't need to do it again) and shrimp played in the water "hide and seek" happily. Rain dissolved into the reservoir, like drops into a large plate, splashing in a string of like pearly drops of water. The rain falls fell (You are writing in past tense. You can't change to present tense mid paragraph) on the horizon, and splashed like a puff of smoke, leaving the earth immediately with a sweet dimple. Light rain to moistens the crops, so that new life, full of vigour, gestates (this word does not make sense here, and it would be very rare to use this word in day to day conversation) is borne in the capsules full of seeds. Let them in the golden autumn procreate.

The green mountain, the tree more elegant, nature becomes more air! It is summer angel! (I'm not sure what this last bit means. You need to be careful with your tenses. Overall pretty good though, I understood most of what you said.)

Many incomplete sentences, missing verbs or nouns or phrases, objects and subjects - deliberately presumably; call it prose poetry and you can write whatever you like.  I stopped 'correcting' for tha reason, it is just a collection of brief incomplete images.
