Goodness, you really can tell that the scanner took its toll on the picture here xDD The texture on this one is quite different from the others. Lol but still it seems pretty good!
I like the blurred effect that you have going around Square here...he looks really suave =P kind of a cool and composed expression on his face, I like that!<3 The clothes are well-done too~ I adore the hat ^^ Oh! And the embellishments with the vines at the top~ they look lovely!!
There isn't much for me to say otherwise~ although for a mini critique bit, the left hand looks a tad bit misshapen on the bottom because of the angle...maybe work on the muscles more in that area? But I guess it might just be my not-used-to seeing perspective xD And finally the way you have the shoulders drawn, it looks like there is a small curve in the shoulder right where the sleeve of the shirt ends? Just make sure to watch how the shading is there ^^:
Other than that, I LOVE this! Keep it up Sage-san!
