Great first concepts, you're very professional and the colour range here is what we are looking for. We've placed you highly because your logos are quite attention-getting. For my feedback:
1) Having 2-5 colours is exactly what we want, though for future entries, a rainbow of distinct colours is probably too much. The 'feather' #24 is pretty slick but that's the maximum clour range we like. Our favourite logo #22 uses multiple colours but is conservative about it because it shades one colour to a similar colour. We'd like to see you use different shades of similar colours for future entries.
2) Can you change the font? Shaded versions of Helvetica and fonts like the winning entry in our competition at
https://logotournament.com/contests/ehealth_training are better. I would also like to see alternative shading options in similar dark blues. Again see the shading in our winning entry.
3) Can you retry the #22 colour cube with the lines slightly closer together? Should be a minor change.
4) We'd love to see any additional logo designs you have... check our suggestions in the brief if ideas. I like the following logos from your portfolio and would be keen to see similar versions:
