What disturbs me is the mix of old and new elements. I hope the cheatline in general get's a rennaisance on the design market within the next years, and the red line on that SNBA aircraft wouldn't look bad if used as a solitaire element, but in combination with the other two things it's just wrong in place.
Also this purple belly. Why does it end so apruptly? Sure it will look bad if farthened over the nose/radome ..but this "T" style thing where the aprupt end of the purple belly and the cheatline meet just looks 3rd calls design!
All in all, the whole SN Brussels Airline CID / Brand design is nothing round .. 3 mayor and minor livery changes within the last months, that just proof that there is no big spirit behind the airline. In my eyes they just care about "yes that looks cool" and forget about a "once created" Corporate ID, another passed chance, another spiritles standard people mover airline in the row of Alitalia, Air France & co.
Look at Swiss! Tyler Brulé never studied design and has created one of the most stylish and "classy" airline cultures in business that go far beyond the borders of design. Design is more than mixing colours with shapes, but that's another story!
just my two cents
BTW, Norbert, why do you change your nickname so often? AirOrange, Vipporbuddy, JetMark ... anything behind it? Just curious.
