Looking good so far... my only suggestion is that the Caribbean Airlines title should be a little bit further back along the fuselage. The "s" in Airlines ends at about the fifth window from the main door. The "C in Caribbean starts about about the 13th window from the rear. This should give you an idea of the size of the logo and it applies to both sides of the aircraft. as for the Tail, you did a great job. My only suggestion there is that the humming bird wing is a bit further back ( closer to the end of the rudders ).
