After assessing the comments of the two reviewers involved in the analysis of the manuscript, I find the work to have some merits, but to be in need of substantial revisions, along the lines suggested by the reviewers. Albeit the sum of all comments point in a direction which is broader than the concept of major revisions, I am willing to give the authors one last opportunity to revise their work. It is not my intention to discount any of the issues/challenges raised by the reviewers. It should also be clear that in case the quality of the revised manuscript will still not be totally acceptable then the work will be stopped and released. As such, in case the authors decide to follow this route, the revised work will definitely be sent out for an additional round of reviews.

After examination of the referee's report, I suggest the authors to implement the set of minor revisions requested. I will be in a position to make a final assessment once these revisions have been implemented. In case the authors do not agree with some of these points, they should provide a strong motivation in their rebuttal.

I see no further reason to delay acceptance of the work.
