Beautiful Ernesta! :D
agreed! Again, the softness is key here - and then the tight focus leading the eye. In terms of your backgrounds, I'd consider using your own soft, digitally painted environments - soft and painterly. Anyway, I look forward to seeing you work with your shaders/lighting/specularity etc. to approximate the softness of your concept art. Really nice stuff!
Ernesta this is gorgeous!! The colours and the tones really make the cells really ‘bamm!!’ out from the background :)
