Critique via comment: Honestly, it's a well made image. The choice of model is fantastic, the costume is wonderful, the stance is great, and the psychic knives effect is nicely done.
If I was pressed to nitpick, it's the graphics and background. The text "Psylocke" and "Super Heroes" are a bit small for a trading card and could be a bit more prominent. The background is good, but it's not evocative. It's an interesting and appropriate set for lots of superhero battles, but the lines of the background don't contribute to her stance, or provide color/lighting complements. A simpler background with a stronger contrast in light and dark (as you did with Tribal Queen) might have worked better because the strong highlights on the model. Maybe? Like I said, it's a great piece, and I have very little to say against it
