Hey Easty, seen a lot of your posts around here. I'm kind of new here to the forum, though I've been lurking for a while.
I think you got some really nice pics there!
Just one thing, if you haven't already done so, try color correcting them a bit (mainly by removing crap data within the levels in PhotoShop). This way you will get a bit more punch in your pics (see below).
These are just suggestions and are not at all meant to offend.
Another tip is to not be afraid to use the sharpen filters in PhotoShop on some areas, just make sure your selection is soft on the edges (use feather function under the selection menu in PhotoShop).
OK, obviously these tips are meant for PhotoShop but can be applied as general ideas of what you can do regardless of application.
Hope it helps.
