Your work is great and all are very creative.

We do not say what is and what is not pixelart but we do say that pixelart added to the gallery has to be controlled on the pixel level and that any tool use such as gradients, trans overlays or any CGd details are not added to these hybrids because it muddies the waters.
We pixelartists all know too that there is no FX that cannot be manually made and we admire and learn from this.

The last pixel 'Road Trip' was very borderline when added because it does contain a bit of CGd bits like the shine on the car, the road shadows and at an even 64 colors the BG is questionable on the pixel level.
It was however added so you got the 'benefit of the doubt' new members get :)

On the 2 revisions here the first is just no longer pixelart at all and the second 'Bus Stop' of course has the light glow (this pixel is great, btw).
Technically they both suffer from lack of control on the pixel level.

You may, of course, use the pencil tool under the art to upload version not having any of the dirty parts and link to the hybrids in the description of the art page, then hitting the submit button again.
