redesigning my aquarium with rock formations

[darkflow]

Did a bit of rock scaping in the tank today after adding those little Cobue yesterday. I've got some pics below - would love to hear your thoughts. Planning to make that left pile a bit higher for when my next fish batch arrives.

Adding some algae to the mix will really complete the look, just need to let nature take its course and it'll be perfect.

I'm thinking of adding some river rock to the mix, but I'm not sure if it'll clash with the other rocks I've got in there - what are your thoughts, would it look out of place?

I'm good with river rock, personally I've got a mix too and I'm just waiting for some algae to grow in and tie everything together, think it'll look great once that happens.
