Love your portraits here! The frog in a suit and the portrait with the backlight on the hair/garment especially look incredible!
The male/human portrait with the vest stands out for me in a negative way—the lighting on the vest itself feels strange to me as it gives it a bit of texture that doesn't quite read as being crumpled fabric and it conflicts with the shadow texture on the crumpled fabric of the shirt arms.
Thanks for making and sharing your art!
