Sorry for not posting sooner.
Don't let it fool you; I’m
really glad to see more artwork from you.
I love the color schemes on both these characters. The spots on the brother are a nice addition.
I also think it’s neat that you put some spines on her back. (Is her brother supposed to have spines, too, or are those bumps on top of the base of his tail just protruding folds of skin?) And as usual, the eyes are so expressive. It looks like the brother’s afraid or reluctant to go somewhere.
Since you stated that these are color tests, I’m not going to bother nitpicking the physical attributes of the characters (unless you’d like me to). The background of the second picture intrigues me, however. Are those dark patches on the rocks meant to be holes, or just shadows of some kind?
I’m having a hard time coming up with name suggestions for a
Diplodocus… You could call her “Doca” (although it’s very similarly spelled to “Doc”, even though the ëo’ would be pronounced differently.) Another possibility is “Carnegie”, for Andrew Carnegie, the namesake of
Diplodocus carnegii. (Do you have an idea for her brother’s name yet? Maybe you could call him “Andrew”.
