When you finish the texturing I'd be interested in seeing it : ) I think the composition on all pictures is well done, as is the lighting. Are you using a picture/world material for the background, or did you model that as well
I haven't used Maya before so I can't say how you'd do it, but the only thing i'd criticize is the lettering not hugging to the blue suitcase! That, and it saying "Jorney" instead of "Journey", but I thought that was charming X) so I like it personally heheh
