Milla and Tayle

Another lovely picture. These two look like a good couple. Although I notice that they don't really have that much of a facial expression, like, what are their feelings toward each other?
Are they shy, or are they not embarrassed by the fact they like each other?
Also facial expression can be based on their personality. Like is Tayle a hot heading rito with a temper issue? Is Milla one of those socially awkward ritos?
It's a good idea to express their personality through pictures like this. Again, it's well drawn but I don't see any message really popping out. I can't tell that much about them just by looking at their designs and blank facial expressions.

So again I'd say one of the biggest things you need to change between this picture is have more personality. Pull the viewers into it. Put detail and thought into your work.
Another small note is their arms are a little too small-next time make them go down a few more inches to make their hand holding more realistic.
