OK, let me try to give some tips.

I don't think that would be enough, but it's easy to fix the problem by yourself.
You can re-upload the drawing.

On the "Upload Drawing" page for the building, you will see the following option: "Select an existing drawing of yours to replace/delete", with a picture of your drawing and a button right under it. Click this button to upload your new version and replace your drawing.

Note that, even though both drawings, new and old, will appear on the "Drawings Pending Approval" page; if your drawing is approved, the old one will be deleted (go to the "Deleted Drawings" page).

Furthermore, you can even upload the original large PNG image which you posted here, under the "Original PNG" on the upload page; however that's not required.


Anyway, hope this advice from an average user helps.
