I hate to say this but the game is a lie I mean when I was little this game was my favorite of all time but then I found out it was just the buchered idea of another game that Nintendo took from Rare called Dinosaur Planet
Of all of the video game/animation characters I know, Krystal is my undoubted favorite. You have drawn her very well. I personally love the shading that you have done. Yet there are a few things that need to be brought to your attention:
First, her tail is too large and is disproportionate to the rest of her body.
Second, her entire stomach area is way too small and narrow. It looks as if she's anorexic there, but in perfect shape everywhere else. It's really weird.
Third, her legs are not the same size and do not match. One has a knee cap,and the other does not.
Fourth, she appears to have two left feet, and has only three toes on each.
Fifth is the very commonly mistconstrued idea that Krystal has white stripes. In actuality, she does not; those on her face and torso sections are only a lighter shade of blue, and "bleed" into the darker blue section of her fur, with no real visible line that separates them.
And speaking of fur, I love the color that you have given her fur, but I think you should that her fur color is actually lighter. That is, if you were shooting for accuracy. Of all of the things that I have mentioned, you can ignore this one. I actually love the way that the darker fur looks.
Despite all of these things mentioned, I love the way that this picture looks. Excellent job.
That is a seriously amazing background. To me, it looks like a planetary nebula somewhere in a galaxy, but it could be other things, too. I also like her staff and her pose - the way she's holding her staff is similar to that of someone wielding a bo staff in real life. In a nutshell, great work!
