First impressions this is interesting... it definitely meets the challenge, and has some great colors.
What are those? It would be nice when you request a critique from the critique club to give us some idea of how you did the shot... or some basic info... it helps us in critiquing more efficiently just for further reference.
Anyway... I like your lighting here a lot. I think it works very well giving the items color, with not too much of a sillouhette look. I think it makes for a very effective shot.
Not much to say about composition here... it's pretty straight forward.
Focus wise, great job. I'm guessing you used macro for this? I can't really tell because I'm not sure what the items are.... but very good job on focus.
Nice job, not overly a wow shot IMHO... but a nice solid shot.
WOW thats all I can say, IMO this is by far the best shot. Meets the challenge, colors and lighting are fabulous, the light blue background gives the feeling like the rocks (?) are floating somehow. This shot has a feeling of depth and suspension that I think is phenomenal.
This is very nice. Colourful yet muted. I love the pastel shades and gentle light. What are they - those glass beans you use in flower arranging? On a lightbox? Very nice.
