Montka: I have to say that the pictures are lacking in contrast.
To demonstrate I've captured two of them and made a side by side comparison with two simple adjustments in Photoshop:
View attachment 3585
View attachment 3586
All I've done is Auto levels and on the Ironclad increased contrast by 5%.
I hope I'm not upsetting you on this but I think that the post production is what needs a little work on it.
Oh and please take into account that the man saying all this is so anally retentive about getting his own pictures right he hasn't submitted anything since 2007.
