Even without looking at your CV....
Europass is something that is very practical and helps a lot when it comes to structure information and how to display it. It looked like a very good idea at the time - about 8 years ago - but it was never accepted by HR. It typically tends to be frowned upon and seen as synonym of laziness/lack if interest. Also, the format hasn't been revised in past the decade, and a lot of water has run under the bridge ever since then.
If you have just taken the europass and filled in the blanks, I would strongly recommend you to make it youra and tweak it until you cannot recognize the format.* There is nothing more personal than a CV, and the way you chose to display who you are will say volumes about the type of professional you are.
One of the bad things about the Europass doesn't include an executive summary and specialties section. Executive summaries were "an anglo-saxon" thing that is becoming increasingly popular. HR has to dig in too many CVs and needs to sort them out very fast. They need to see their favorite keywords on the first 3 sentences...
As you specifically mentioned you are in medical writing, just basing your CV on an obvious pre-set format might not be a good strategy. After all, your line of work requires that you find optimal ways of showing data and information. Using a set format reads like cookie-cutter and one-trick-pony. I would expecting a bit more thought on how to present data, which is basically the job you are asking for.
Finally, I see where you are coming from by asking your peers. Yet, you might get more benefit if you ask someone who is with HR departments or recruits people. A fellow scientist will only tell you what you already know. A HR person might tell you how they perceive your CV and what they look for when they screen it. Personally, I got more valuable feedback by asking people totally unrelated to my field of work than a peer. Scientific CVs are very specific, but so is IT or engineering.
Hope this helps!
*Mine actually start as an europass, and was worked, reworked and rereworked. The only thing is left is the middle strike, because it is esthetically appealing and I am posh like this.
