In the gallery of your profile maybe you can cancel the submision.

Is there a way to delete pixel arts, ordo you just have to rename them and change the file?

I think you can submit all the burguers in a same file.

I like the but the could be better with more contrast, more detail in bread and other ingredients and picking another colors to the border line, not the typical black one.

I'll do that.

Why not put all images of the series in one big together image?

And please remove the white background: make it transparent. You can do this on www.iaza.com
