FIRST IMPRESSION: Good composition, cute twist on the subject!
CHALLENGE: Meets the challenge even if these aren't transportation quite yet. Maybe they're more of a concept vehicle at this point? ;-)
COMPOSITION: Excellent composition, the position of th efeet relative to each other leads the eye in a circle and helps keep the viewer's eye in the shot. The blankets also help with this.
TECHNICAL: Good exposure and lighting. The light is strongest on the toes, which are the most interest aspect of this shot. The black and white helps accentuate shape and lighting over color, which is a good idea here. The disadvantage in this shot is that the black and white also leads the texture of the blanket to compete with your subject for the viewer's attention.
CONCLUSION: A strong entry, unfortunately black and white almost always gets mixed reviews here, especially when it produces both benefits and drawbacks as it did in this case.
Thanks for sharing and good luck in future challenges!
