Thank you for all your comments, everyone! I've never been very confident about my art, and I was unsure about starting commissions, but you guys have all helped so much, and I feel like I'm really improving, so thank you all =)
And Tommarrow, I'm really glad you like her - she was fun to draw =D
Mistical Miss - You're so right about the eyes - the more I worked on them, the more determined she was to stare at the blank space in front of her instead of the titan, so I eventually had to let her be >< To turn them lower without making her look surprised would I think have meant narrowing her eyes, which I didn't much want to do... Eyes are always the hardest part for me ^^'
Milennin - Thank you so much

I don't use anything too exciting for my pictures. I actually draw them in Paint (from which they come out looking something like this, if anyone's interested =p), and all the rest is Adobe PS7 - One day I'll learn how to use Photoshop properly, but for now it's just the brush tool for me xP
