Ok...this is just my own personal opinion here, however I find myself asking, what was the point of shooting these as (or converting them to) b&w? "Kids" and "critters", to me usually lend themselves to vivid colors. While I did in fact shoot a good amount of black & white back in my earliest years of working with film, today I don't do such conversions unless there's a very specific reason to...something in the image that would lend itself to b&w to help create a specific mood or feel. While these shots are interesting, well framed, etc., I just don't see how the use of b&w really adds anything to them...in my mind the image(s) should convey some specific reason or intent for such usage.
Again just my own opinion.
