Use Sticker to draw a large area

[yyakun]

hello

When I use Sticker to draw a large image of an area, the black area occasionally appears and fails to be drawn. Can you help me see where the problem is?

The smiley faces are stickers too so that should work.
I notice it's a very large area. I'd see if that image worked with a smaller sticker first.
