It could work, but I'd suggest that you look at the 2014 Aquascaping Award winners and get an idea about the Rule of Thirds + visual balance.
Your tank has two focus points right now: the 'left' and 'right'. The left side includes your stone placement (which is fantastic, by the way), and the right side includes your driftwood. They're struggling visually right now; viewers are trying to focus on both at once, which is why it's really hard to 'get it right' in a tank with two focal points.
Here's what I'd suggest:
Trying incorporating the stones into the driftwood, similar to a natural streamside. The driftwood could naturally be 'growing' over the top of the stone, and it'd create a beautiful focal point to your tank, and it'd also give you some greatly-needed open space.
Additionally, I'd consider using a few smaller stones to emphasize scale. Scale is what makes those Award-Winning tanks look so beautiful: you can't even tell that they're mostly 10 gallons or smaller.
Hope this helps!
