Different types of sentences

In Hur3 we have been learning about different types of sentences like Very short sentences. We had so make a simple sentence into a complex sentence. That was the start of our paragraph. We had to do one very short sentence and 2 W-starts sentences. The W-start is where you choose a word out of When, Where, Whilst and while. Here is my paragraph... 

This morning he ran away yelling in the forest madly. He ran and ran as fast as he could. Beside the river, beside a lake and into a swamp. The boy sat down to rest as well as eat something. He heard it. He heard something that changed his life. Gun fire! The boy got down and hid from the enemy team. Whilst he got up in a good position to snipe them, he got hit, “Hit!” the boy shouted and put his hand up. While he was walking back to respawn, he knew someone was following him. “Could I just respawn?!” The boy whispered.
