its good and all, but nothing special. i mean, you've been doing this for a while now, right? dont you want to step it up a bit? to me, it looks good, but its nothing advanced. the same old stuff, kind of. try to add some new dimensions to your work!
oh, and you really should shrink it down. personally, i would if a panel like that was never bigger than 600 pixels wide, or 800 at the most. why? because there's nothing much in it, just a face. when you cellshade such a big area, it tends to come out flat and especially when its that big. if it was soft shading of matte painting, it would be a different story tho!
