In this case, I just read the comment about this design beings so "original", and I disagreed with there really being any originality with anthropomorphic planets walking around each other.
It is possible that the person who left that remark had not seen walmazan's design. People come and go, and don't necessarily check woot all the time.
There are tons of designs out there depicting planets, the moon, etc. A few artists here, like walmazan and wirdou, and now naolito, who have opted to depict planets this way. The designs aren't the same and the elements that overlap are so basic that, at least in my perspective, it's not an issue. For me, I liked what naolito did in terms of the expressions and actions and that distinguished the design from others. Just my 2 cents.
