You should have updated the other upload and not submitted this as a new spray FYI. This is not a new spray after all.
While it looks better though, you really should have taken more time to better clean it up. As it stands it looks half-assed and keeping the shadow for the wall doesn't help much either. For that I would have removed it and made a new transparent shadow behind the image. This will help it look better on all surfaces you spray the image on regardless of color and what not. Other wise I would flat out remove it as well if you don't want to put in the effort.
