Appreciate the work. At present the camera surroundings look a little unnatural, somewhat artificial. Perhaps that can be enhanced for a more realistic look. The lenses could still do with a little work, as there would not be two identical lenses installed.
About coloring, I fancy soft colors. But I donno pal, I´m unaware about the target group for the 2a, but putting (much) more color on it will surely impress my toddlers.
