looks pretty good, im sure Arcane will be here soon to critisize you on the poly\'s... but i thinks its alright
it would not be that hard to texture, if all you wanted was maybe a stone texture... search google for stone texture. then jus slap it on, i dont think you will need any mapping. if you do, im not your man

EDIT:: oh, and if you got some help, maybe you could include a falling water animation, then it would go ingame!
