I like the flow of the wood. The only thing that's a little distracting is its looks like you have different types of wood. I don't think that would matter if you planted the left hand side with some epiphytes to cover the larger chunks, perhaps with some emersed growth on top, and perhaps cover the tangle of wood in the centre with some lower growing bucephalandra to cover all the gaps in the branches. I think it would look really good like that, transitioning from heavier planting on the left (as we look at the picture) to more open area on the right where the nice wood branches are.
I say all that without the vision of skill of an aquascaper. So hopefully one of the more knowledgeable folk will give you their opinion.
