This is so lovely! Now please animate!
Maybe the greens are still a little too harsh. Maybe.
The 2 platdforms on the right look too thin too.
Really appreciate the feedback. I'll have another go at the colors tonight.
I don't think it needed to be changed to blue neccessarily but do you notice how it now looks to be in the background as opposed to the previous orange looked to be in the foreground?
I actually think your color choices are not the best and could use some further exploration. For example the road lines use a shade in the brown palette as does the smoke coming out of the car. Maybe these 2 items could share a tone that could also be used in the sky. A light desaturated blue/grey, for example.
Again, its a clever idea and would make a good real game. I don't mean to rant on your art. I like it and just want it to be awesome looking ;)
Nice mockup and good game idea. I don't like the sky color because it fails to be a background and almost overpowers everything else.
Very cool!
