I made a 48x48 farm for a server challenge.
Looks best at 2x
Shoot, I'm sorry, I thought it was at the original resolution
I think this is one of your best pieces.
You don't need to pre-zoom your art on PJ, it's best to submit at 1x and let people zoom how they like using the zoom buttons. If you have a preferred zoom level for the piece, you can mention it in the description.
