Very nice image. Well shaded and interesting colours! Instantly recognisable character even though I haven't played FF9 myself.
Just so you know, pixel art isn't just about using low resolution; it's about using a limited palette and drawing with only simple tools. It looks like you've used a soft brush that mixes colours, resulting in 235 unique colours. Next time try limiting the palette a bit to get more of a 'pixel-art' look to your images.
Gennoveus is right. Unfortunately, the use of soft brushes does disqualify this from being pixel art, meaning this can't be accepted into the gallery in its current form. For sprites of this size, I'd recommend sticking to just the pencil and fill bucket (and turning off anti-aliasing if necessary).
