I like the new colors. They are classy, clean and fresh. The tail looks event better than I hoped it would. The billboard titles are not too large and they are positioned a bit towards the middle section of the fuselage, so they wont be covered by the jetway on the gate stand.
I like how designers managed to make the new livery look Serbian but not too much. The livery is modern, but not extremely fashionable and in danger of being outdated in a year... no swooshes, no gradiants, no wings etc. Not bad, not bad at all. And the red belly logo

Total surprise. A nice touch, nice indeed.
