This is great in every way shape and from. The animation is well edited, the colors chosen for the characters mach in a special way with most characters having cold colors for there skin. Plus the way characters appear to be more saturated with color then the background making the characters stand out from the scenery. Plus it's nice to see the repetition of colors like blue and dark blue being used for the secondary characters and lower parts of the main character. The two brother characters also had unique colors for there shirts; one having a turquoise and the other having a hot reddish pink making the taller brother somewhat more aggressive. The terrorist's reddish color is close to the Brent's skin color, but is less saturated making the terrorist less confident than Brent. The sky marshal has colors close to a dried up version of the sun that looks confident with his red tie and jolly creamy yellow skin, but turns out to be overzealous (enthusiasm in pursuit of a cause). The backgrounds are drawn in a cartoon style special to the artist that has a slight bumpy outline with a smudgy gradient textures to shadows, yet gives the backgrounds its own special character. Story is good and it flows nicely though to be honest I got confused after the terrorist jumps off the plain, what made me confused was when Brent says "Are plain didn't even take off," yes that makes since, but I guess it was just worded in a way that confused me because it makes it sound like the first plain they were on wasn't THERE plain. But all that aside the jokes hit sound was good and humor started strong and built up to a satisfying ending, though It might have made more since if Brax was happy that they missed the flight since he was so adamant about missing the flight to begin with. Yet the realization form both characters at the end is priceless. The motion of the characters is smooth and the exaggerations in boy movement are on point. Line quality is clean and perfected. Sound tracks for the beginning has a nice build to the whats to come and the ending sound track is rewarding and properly shows off the creators of the animation. Sound for key actions are mach and add emphasis to movement. Voice acting is confident, clear, and playful to the point that the voices fit the character (I especially love the Sasquatch guy). Volume isn't to loud voices are clear, background noise fills the space, all scene changes fade there audio out nicely so as not to be to sudden for the viewer. Film length was perfect, didn't have any scene what so ever were I was like get on with it, it was straight to the point.
I would like to see improvement overtime with backgrounds, making things more cleaner like smother lines on objects, and corners of walls and also adding adding depth to your backgrounds so it all doesn't look like its all on one level (yes there are shadows that convey an object is on top of another object in the animation, but not enough to make the object feel like its going back in space realistically. So I recommend having a slight increase in shadow strength, more detail to light and how it shines against surfaces, also maybe try soft cell shading to give shadows more of a detailed texture. these were just suggestions to try out.) But end the end the background isn't the main focus, the characters are, and they do stand out nicely.
Great job all around on the animation, keep up the great work!!! ^U^
