UPDATE: Began Water tiles, now I need those transitions. Added some variety to the border tiles, working on expanding that to every transition. Also added a character test sprite, and a horrible one at that. No surprises there, really.
I would seriously appreciate any advice you can offer in that area. The examples with images and edits have helped the most so far, I'm more of a visual and tactile person than I am a 'read-em-an-learn'.

^ UPDATE: Base water tiles for the Water -> Wasteland transition are done. Now for detail tiles.
UPDATE THE II: Hey, all, tiny internet hiatus there, but I'm back.

There's an update for you. Updated the water -> grassland transition, and added in a test abandoned building. How does everything look? Please do C+C and make edits. After all, I want this game to look good not just to me, but to you guys as well.
