I like option one. Having some extra protrusions in the upper reaches of the tank will give more space to mount epiphytes, create some dramatic shadows, and may encourage the frogs to venture up higher, depending on species.
It depends on plants. Sometimes I've found myself spending way too much time on getting wood or background components just perfect and then realizing that I didn't leave room for some of the plants that I wanted to use. So if you're using some larger terrestrial foreground plants, might want to back the wood up a bit. If you want a larger vine on the background with some smaller epiphytes on the wood, bring the wood forward... and so forth.
I actually think it's really cool looking wood and all of the layouts look great, just looking at the wood. I just thought I'd mention really thinking about what plants you're going to use and their placement, since I've "underthought" in that area at times.
