Hi -- these are very interesting! I'm wondering if #38 could be given the same head (yin/yang) as #48? Overall, these are going in the direction I'm looking for, they are abstract, they "flow" like T'ai Chi, and they even have a bit of Chinese character feel.
Dear Hendraku, Of these three new designs, I like Entry #70 the best. It is clean and I can see it would go well on a variety of media. It is still making use of a generally T'ai Chi image (good). On the other hand, it reminds me a lot of a number of other fitness logos here in the US (you can look at www.ideafit.com, for example). The other two designs are very fun, but a bit too cartoonish for what I want to portray with this logo. What I continue to like about all your designs is the sense of fluidity and (the more I look at them) their dimensionality.
