It would be helpful to at least start the scape so we can get a feel for what you like and where your headed. As for tips, i watched a bunch of youtube videos on the subject, looked at a bunch of show tanks and read these forums for a while. Way too much info to try and encapsulate in one post. Sorry, i know not very helpful
I agree with fj - it would help to see what you have in mind. Show us some options to give a sense of where you're going with this. You mention a Dutch look, but I can't recall seeing "branchy" driftwood in Dutch style tanks (although I suppose that's where the "jungle" part comes in).
What I want to do now is dry start the tank to get a carpet of dwarf baby tears. After I fill up the tank, there's two ways I could go. I think I want to use jungle val around the back center of the tank, mainly behind the driftwood, with some smaller/shorter plants around it. I may add a few reddish ones just for contrast.
