Hey Dave,
Nice job with the conversion. I like the seperation between all the objects. I am debating the strong dark shadow on the LH, middle ground side. Did you try lightening it B4 the conversion as it seems out of place tonally with the rest. Crop would work too but I would check to see if you could bring out some detail in there.
Nicely done, Dave! The repost really adds to the piece. This almost has an IR feel to it - was that your intention when you did the conversion? It's very interesting!
