#39 - I actually do like this logo. The font, balance and weight is pretty good. Although I typically prefer straight lines to rounded, the mark is pretty appealing. I would love to see some other variations of the mark.
#40 - Similar comments to #39, but don't like the mark. Something more balanced, with less curves would be more appealing to me.
#36 - Color is not right and the mark is a not strong enough. I also prefer to highlight "Impact" more than Payment Systems.
