I can't figure out if this is the same artist or not. Their sites are linked together, but their work seems to be different styles.
yukino_minato and tamago
These two websites link to their blogs:
http://www.noraneko-no-tama.com/
http://www.yotsumi423.com/
In the artist entry for Yukino Minato, they belong to the group "noraneko_no_tama". Should both artists just be added to this group and leave them separate?
