Three Junos; Alabama, Florida, and Mexico

I haven't done a lot of still life images myself (I shoot mostly

nature) but have started to think about images derived from my large

shell collection. I am going to work on abstracts from these

specimens and would appreciate any constructive feedback that you can

pass along, especially since this is a new direction for me to move my

photography into.

Looking at this one there is a bit of a reflection even though I was

shooting in a softbox. Should I be using a polarizer?

Thanks
