Please review my CV, feel free to tear it apart

I think it's fine. I guess the only comment I have is maybe try to give a bit more details on certain points. Like: "Responsible for client and potential buyers presentations"

well... anybody can write that

"Prepared over 20 presentations overviewing XYZ for clients and potential buyers. Learnt to do ZYX."

I think if you decrease the page margins (look huge) and add more details you're good. Also why "GPA" at EU uni? Is that what you use in Greece?

Also note: - presentations for potential buyers, or - potential buyers' (note the apostrophe) presentations

IMO don't list the years on your degree. Put down; "Class of xxxx" if it really took 10 years to graduate.

Alternatively you just can take off the part that mentions it is a 5 year program.

I would separate your two degrees if you have two different cumulative grades you can use, or just list the MSc GPA if it is high.

–make the font a serif font (Times) –your margins are greater than 1". make them 0.6-0.8" –all bullet points must go at least three-quarters across the page –bullet points need work. 'Trained mktg team' Trained to do what? How?

Start with that. Feel free to post it again.
