The sireneflashes are non-pixelart, looks like you scaled a picture of a car, used some radiants and forgot to re-color some parts.

I'm sorry; but I am voting "no" on this. I'll be looking forward to see this piece redone so it meets pixeljoint' standards.

Looks good, although I do think you could greatly reduce the color count. The hood of the car almost seems like you used a gradient fill or something.

Yehaaw, a hip hop reference.

Nice, although the flashes are not visible enough!
