Yes you can, your design its very outdated.
Mmm im not sure, but looks nice, good luck
Same happened to me, you focus on features but the design is nothing unique. But this time really, you have great and very creative items, reviewers are more vigilant than ever aside designs that having some months old. I must admit that they let some exceptions that i do not understand, but that does not concern me i guess. So , i like the theme, very neat. But well you know, maybe you can add more unique blocks.
I found the design outdated but well , as people said start fixing the errors.
I think I know exactly the reason why your submission was rejected. You’re trying to upload a PSD which is for Photoshop and a PSD is essentially just a photo, ThemeForest is meant for themes like WordPress themes, webpage themes. You should upload a zip folder with the contents that make up this theme that you are trying to sell on the marketplace. The zip folder should include the following: any .php, .html, .css, .js, .png, .jpg, ect files that make up that theme. Of course you can include any PSD files, but cannot be the only thing uploaded as that would not qualify as a theme; instead it would more qualify for Graphicriver, or Photodune.
