I was assuming, on average, Anterians would be about the size of a big dog. (maybe 4 feet, if standing on hind legs and standing more or less straight). I really can't imagine taking a cat-sized opponent very seriously in a battle. Magic or not...
"Aww...look at the cute little lizard!"
::bite::
"Argh! Stupid little bugger!"
::Steps on Anterian with a funny little squish sound effect::
^_^ It brings to mind, somewhat, the whole Puss in Boots thing from Shrek.
As for look, I saw them as slightly more sleek and less "dragonishly" bumpy and scaly. This might help the personability factor ever so slightly.
The second picture, "Akio-Dell" was closer to what I was thinking. The third one is far too Gargoyle-esque in my opinion.
It would be interesting to bring in some ancestry to this. Maybe Anterians and Dragons somehow COULD be related.
I like the first picture, even though it doesn't fit my idea at all...but then I got to thinking. What if there was like...battle armor or rank signification or something like that...
Because in a lot of cultures, current and otherwise, the leaders and more powerful individuals are ornamented or decorated in some way, whether it be military bars or special ways of dressing or stuff like that...
Well, that's my idea, at any rate.
