Hi! Your art is so cool!! I made both of their hands and the blue character's front leg bigger, because objects that are closer to the camera should be bigger (foreshortening). I think it makes it look a little more natural! I darkened the bottom, since I felt like there was kind of a lack of visual hierarchy contrast-wise (as in, no area had more or less contrast than another). Now, the area around their faces and hands have higher contrast than their legs and feet, which makes them stand out and make them easier to focus on. This is also the reason why I darkened the background a little, to increase the contrast and make the characters stand out (especially their heads). The last thing I did was add some shadows at their feet to make them feel more grounded, since you already added a floor. I love this piece and your characters are so awesome!! I hope this helps! | Artwod Feedback
