No Support I think the grass ground (I think it's grass) would not really look that nice with people who have a default texture pack. Just make sure the down looks nice without a texture pack on. Same with the walls. Try adding more details to the walls and floor. That's about it. Good luck!
No support I really dont get the feeling Adding cobble stone for wall's?Not a good idea Put more effort into this as well
No support. - I like the outside design, but maybe add more design and change the cobblestone idea... -> Cobblestone change to something nether related??
No support, People without a texture pack would honestly hate it. Changing the blocks would make it much better.
