Tallon Picture: First Samus: Second Samus: Third Samus: Special Blending/Effects: No arrows.
Overall:
Reasons: - The Tallon pic on the background is too blurry. - The first Samus (the one on the left) has some stray pixels left here and there. Meaning the cropping could be a little better. - The second Samus seems to be the best extraction job, but still has some stray pixels left. -The third Samus, compared to the other two, is a stray pixel fest, and also has white stains on the crotch area. - The wall could have used some blending effects, or some Special movie-type F/X to give more emphasis to the poses of the heroine, while still maintaining the attention on the planet in the background. - Bonus negative points for excessive simpleness, and not leaving the users enough space to put their icons while still being able to admire the wallpaper.
Overall a decent piece, but still has more than enough room for massive improvement. Sorry if this sounded harsh, but it's my honest opinion.
