@kronos, your map looks fine except for the snow/grass mixture... The ledges going from left to right are fine, there's nothing stopping a player going from a town to the next HAVING to traverse through lot's of grassy patches but coming back VIA a ledge, Pokémon RBY did it from Viridian to Pallet, why can't you do it... And from Cerulean all the way to Vermillion, you could avoid every grass patch of you wanted... P.S, there is already a tree with a snowy base.
Your town is too spacey... Fill it out a little or shrink the map a few sizes... Otherwise, no complaints (except the snow/grass mixture as before).
@KirakonGxi, your map looks pretty good, except the double house, needs some spriting work for definite, your fences need to have an end part of the fence, but everything looks pretty good in my opinion... I don't like, however, the mixture of picket fences and log fences, stick to one or the other (the log ones look fine), although the picket fence on the west most exit is fine as it is, but the mixture of logs looks awful... The city also has a height of 2, but the west most wall has no end, lowering the 1 wall then adding the 2nd will look much better.
@Elarmasecreta, I don't like those tiles, prefer HGSS style or DPPT, but from what you've made, it's pretty basic, nothing pops out, there are no obstacles so the path is pretty clear cut, quite boring if you ask me, give the town some life, the entrance to the town (south), is a little large, I never liked large entrances unless used well, in this case, I don't think it is, I think adding trees would suffice.
@kronos, kirakonGxi and Elarmasecreta... I like the tree layouts, very natural.
