I'm kind of neutral on the Aloha livery, not against and not with it. The colors are very bright and do have a tropical sense to it. However, it might be too bright.
As for the Turkish Airlines livery on the liladesign website, that one is a bad one. The idea is good, with the blue eye on the tail, a symbol for protection and strength in the turkish culture, but the red colour should be retained for Turkish Airlines. The red colour is the trademark for Turkish Airlines. Going away from the red is not a smart move and don't think Turkish Airlines will go away from that. The crane on the current tail should be (slightly) changed but keep the red colour. It's the colour of Turkey's flag. What I thaught was, to write Turkish Airlines in both Turkish (Türk Hava Yollari) and english (Turkish Airlines). This would give their livery both an international appeal (english language) and national appeal (turkish language). I know some turkish people and have been to Turkey as well, they are nice people.
