Here's some advice from me, Cropping out the borders before uploading the image will make it look way better, Than keeping the borders.
I normally do, yep. That's one of my biggest things I look for, but in this case, it seemed right to leave the "dangerous Worlds" logo. It seems to be a series of pieces that the artist makes. I thought it might be best to leave it for those that might want to follow more in the series.
When the borders are completely black though, I tend to crop them out.
