for the water thing, i see the problem, the 2 water tiles you have shown, one is marked 0 (which is the animated one, it should be marked 7 so that it actually gets to be water) and the other is marked 7 (which is the flat one, it should be marked 6 to get reflections)
as for the sand, if you are using the sand in the top row, then it's because it is marked as 0. change it to 3
and lastly, nice sign, i take it you are making your own tileset? and also, where on earth did you get the ash sprite? O.o i've been searching and can't find one. i've resulted to spriting my own stuff now (i have already sprited a team rocket, but i used the colors of the ones in pokemon orange)
