This has nothing to do with my art. Alrighty then, since you want me to add on to my comment; Since my views are an opinion, I'll get into critique.



Since the artist is using a base screenshot/splash art as his base; He should work on smoothing our the sharp edges on the figure. This will give him a much smoother linework, and provide the image something closer to the splash he used.



Example, the right leg and left hip area of the costume are sharp and differ from the original reference slightly, which has a much smoother silhouette.



I'm guessing the artist, wanted to go for a minimalist approach and that's fine. The figure is flat against the background, and doesn't really pop, if they were to add a slight under-shadow to the figure, it would separate itself into the foreground, which allows viewers to focus more on the main aspect of the image and that's D.VA. Right now, without any detail work or basic shadows, the eyes tend to wander around the piece in a random way.



Walid can fix this by adding some shading to certain areas of the piece and slight details to pull the viewer's eye in a direction that he wants them to view it. Example, top to bottom, or left to right.
