Those look like screenshots that you just slapped a filter and logo on. I get that your prices are low but maybe you should make a few examples with characters or effects using blender.
@DimbleGames Wow I’m offended you called my examples so called “Ugly” as this piece of work was in line with what the group owner wanted. Thanks & have a nice day!
He is correct, however. This is a screenshot without UI, a filter on top, and a logo. The thumbnails are fine, however, the logos wouldn’t be acceptable. They need to differ from the thumbnails and at least have text.
Considering you use Photoshop, I was hoping your examples would be better that this. This would make sense for what I use (Pixlr E), but with photoshop you can add amazing effects, not just a filter.
