Jans here's a scape I did last year using branch type driftwood, I used cable ties to hold the join them together if needed, and then I used a large piece of bogwood as the central base which all the branches are tied to somehow, gotta be inventive for that bit to hold them all from falling down.
This was the basic layout with the driftwood
I then just built the plants up around it, added a bit here and there.
and it finished up like this
I would just spend some time playing around with the wood at your disposal, you would be surprised at what you will come up with, there are probably many different layouts you could do with the same pieces of driftwood, just in different combinations. I saw the wood in the buy/sell section and it looks great, best of luck with it.
