COMMENTS:

CAPITALS = corrections

Dear Sirs - We have to be less gendered nowadays, because you don't know who the people are "to whom it may concern" is a set phrase for situations like this.

Inquisitiveness – I think ‘curiosity’ would be better and more natural. Even though inquisitiveness is correct, it sounds to posh.

Certain liberties – I understand what you mean, I would put down why you have “certain liberties”, because it will be the first question you get asked at an interview. “Certain liberties”, when I hear this phrase I feel uneasy, it’s hard to explain…this is a bad justification ;) sorry. Use it if you want, I think it would be better to say “I currently have the capacity to take on my work…”

“I HAVE developed MY presentational skills, communication skills with different languages and culture as well I found out that good interpersonal skills, high resilience, being self-initiative & independence are also my strengths.” – I just made this sound more formal, same meaning.

Hopefully this helps, if you have any questions just contact me ;)
