@CukiArtist very cute artwork, I am especially impressed with the dog! I like what you are doing with the expressions. The thing that sticks out the most to me is that the alien and girl look very similar to each other in design (same length of hair, same eye shape, "wings"). What do you think about changing up some of the features to let them compliment each other. Maybe try the eyeshape on the girl to make her look a little less fairy-ish and see what you think.
