I like how the set-up of this is pretty evident, thus making it appear more professional, perhaps?
The stance and expression work well to convey a sense of attitude, almost, and yet... the colours soften it up a bit. I'm not sure I'm fond of the colours as such. For me, it's a bit too pink and warm... and possibly bright as well, but it's not bad overall.
I like the centre positioning and how you've framed it, anyway. My main issue is the tone. I don't think it would hurt to darken it a bit whilst maintaining the contrast, but that might just be me.
