Great pack, love the style! Just one issue.
I tried importing this into RPG Maker but it seems the tiles were too small :( How do I fix this? 
I don't use RPG Maker so I may be wrong here. But they set their tile sizes to 48x48 right? These are set to 32x32 and wont scale up to 48 properly.
I would try finding a plugin that allows you to change your tiles sizes! Looking on the forums I found these:

Like I said I'm not familiar with RPG Maker but I think it's a little strange you can't change your tile sizes.
I know this comment reply it's from 4 years ago and stuff but I think I know why the format were to small , I assume you're using RPG Maker MV... this tilesets are 32x32 which engine that support that size of tileset is RPG Maker VX ACE
but even with that you have to edit and format it you're own to make sure it's worked on the engine ;-;
