All my tilesets are 16x16, so if you need 32x32, you can just resample (resize) by 200% (nearest neighbor) to get what you need.
Just be aware that you may also need to move some things around, or split the asset into multiple sheets, in order to fit within your game engine's tilesheet resolution limits.
As long as you scale in whole numbers (x2, x3, x4 or rather 200%, 300%, 400%) then your pixel art will always look good. So any multiple of 16 will work for this asset: 16x16, 32x32, 48x48, etc. If you try to mak,e it 24x24, then you'll ruin it 🤷♀️
One last thing, since I'm guessing you're using RPG Maker? Don't expect the autoiling to work. RPG Maker's autotiles are half the size of the regular tiles, mine are consistent. You'll need to place all your autotiles individually here.
