I really love these two!
However I think some of your recent updates (THEY ARE REALLY PRETTY) are a bit lacking in focus. Maybe try to tone down the sparkles a little and have compositions that draw your eye to the focal point (like the Canaan one, where the C4D really goes with the flow). Rule of thirds also works well for signatures, so try placing renders off-centre once in a while! Really great work all in all, keep it up!
Just a question, have you ever made any sigs with male characters?
