Thanks Peter, I actually messed around with Arsheesh's method a long time ago and could never get results I was happy with. Others have gotten it to work really well, so the problem is clearly not with the method

For a second stab at this I took everyone's advice and tried to break up the monotonous expanses of single texture with more climate-appropriate variability. IMO it's an improvement, but as always I'd be very curious to hear others' thoughts and opinions.
