If ya got Paint Shop Pro (10 or higher, I think) or Photoshop, then there's tutorials there on it. I'm pretty sure you need something like PSP or PS to do it, so that's another thing you might want to consider investing in. PSPX2 is only like $100, as opposed to $600ish for PS.
You definitely take very nice pictures. Its just the camera that is holding you back. I don't know if you want me to edit your photos so if you say no I will take them down. But I did a very little bit in photoshop to take away the haze and you can see if you like them more. I can tell you what to do if you have photoshop.
