hi xray - welcome ...
#224 is a bit too masculine/severe looking ... even if i was a guy, i would be a bit too scared to put some of the product with that logo on my face! i like how you have thought of making the design different and so have tried the same colours, but i think even if the colours were a bit more subtle it still isnt what i am after
#223 i like how u have tried to take it a bit further by putting a line between the two i dots, i have to have more of a think about this one, i think the line might be a bit too severe and takes the focus of the name skin engineer
#222 because engineer is highlighted i think it takes the brand down a notch to more generic, rather then premium, particularly in the bold font you have choosen.
tks very much for your designs - hope this feedback helps!
