no flow, i dont like them at all, colors dont match, if you cant get the color to match, gradient black to white. 2/10 if i had to rate but make flow...find tutorials otherwise...gj?
If I had to choose any I would pick v3 but they could still use work. there a little plain. Add some affects, a blur, and a photo filter or two.
Add some flow, a defined light source, a better color scheme (gradients don't make everything ya know), and a border.
