Don't doubt yourself it's sound really good so far. Although it's a little awkward in some places put I'm sure you can work it out and think about adding a little more detail. Maybe throw in some small physical characteristics to describe the main characters, like hair/eye/skin color, thin, wispy, tall, lanky, skinny, large, chunky, thick, stout, over/under weight, delicate, strong, weak, brawny, puny, shape of eyes/mouth/nose/ears, etc. That sounds like a lot but I'm not telling you to add all of those things at once or at all. If you do choose to add some of those, give them to the readers a little bit at a time, don't overload the reader's senses.
Like some of the others said, u rlly need to add description. Use more imagery and sensory language. Develop ur character's personality through his surroundings. That ounds weird, I kno but like...state how he feels about certain things. Add connections to his past when certain things are mentioned. Kind of slowly unlock who ur charcter rlly is. And rebecca_m_15 is rite. Don't doubt urself. be confident, if u aren't...ur writing will take a hit. Sure, u may not be a best seller on ur first try but believe in ur writing or ur doubt will show up in ur story. Good luck!
