I know that similar things to this have already been done, I just wanted to check what could I do and mess a bit with it. You can also replace the bottom water with dirt and it'll look like a waterfall that makes a lake.
Also, I added many sprites. Not to hide the blockyness (some of them are for that

) but most of them are because I just wanted to add them, because it looks better. Don't start with "OMgmgmgomoG SPRITE COUNT!! TOO MUCH SPRITES!! SC WILL CRASH!!"
