In addition to Felix's helpful comments above, I'd like to add:
You have <s>abused luminous</s> colours, I'm not feeling comfortable at your home!
I think instead of "abused," you could use "overdone," and "luminous" is meant more for things that emit light. Personally I would say something like "you've overdone the bright colors in here" or, for the sake of using more advanced vocabulary, "you've overdone the vibrant colors in here, I don't feel comfortable in your home!" As an aside, it's more natural to say "I don't feel comfortable in your home" rather than "I'm not feeling comfortable in your home" although from a purely grammar standpoint I'm not sure why.
I frequently mess up my bedroom!
"My bedroom is frequently messy!" is how I would phrase this because messing up means a making a mistake

Jason is idiotic! He works as a waiter in a restaurant. His last <s>bloomer</s> was, when he brought 42 coffees, instead of 4 tea 2 coffees!
I think the word you were looking for is "blunder"
I'm so indolent those days, when I'm at home all the time, I'm not as prodactive as previously.
"proactive" and "productive" are words that fit here, not sure which one was meant to be used
Nice job expanding your vocab and bringing it into active use! You should consider putting posts like these under "notebooks" next time as you will likely get more feedback
