Rocks!!

I have been sculpting rocks for a bit, these will surround the tower in the little corner I'm making for the scene.
I've been experimenting with 2 types of rock formations and I'll probably be going for a developed version of the second image I upload. This was my first try:

And heres is the second version. Which I like best and will be developing further, as I think its not quite there yet :p

Retopologising these is going to be a PAIN!! haha but its got to be done!
