This is a great piece; the color tones are very nice and subtle -- the craft reminded me of one from the Thunderbirds I used to watch as a kid (Major difference: this one's bigger in scale, and the tail section is notable)
selicial-chan yeah you should buy a tablet. The bamboo series is not THAT ex, and it really really helps your drawing skills. At least it helped me very much. Maybe you can look for a 2nd-handed one from ebay.
