well, the tiles are alright albeit a bit boring and nothing I havent seen before, but what I think the main problem is is that nintendo has already done exactly what you want to do, zelda BS anyone?
Ya, I'm well aware it's already been done. Doesn't mean I don't enjoy doing it myself. It was my way of seeing if I could manage to get some tiles done in an 8x8 limitation. I don't really know how to get it anymore 'entertaining' to stop it from being boring without drastically going in another direction with the tiles and pulling away from a simple style that Zelda has.
And I'll try to rid the dithering. It was something I messed with going back and forth, but just couldn't get a smooth, but good look going, so I just went with dithering.
Thanks.
EDIT: Here's a cave edit:

And for utter comparision, BS, Classic, and mines:

I try to keep with the simplistic Zelda style, but not exactly copying or merging with the BS tiles.
