I have to be honest, Nezha looks rather a lot like a Chinese Sari Sumdac, which would be less of an issue if he weren't...well, a he.
It's an interesting idea, combining Transformers and classic Chinese characters, though my complete lack of knowledge of these particular individuals means I can't really comment on how well it's pulled off. Myself I'd rather have Chinese mythological characters rather than these somewhat more contemporary ones, just because mythology and Transformers mix well, Chinese mythology is rather cool, and the idea of a Chinese flavoured Go! would be neat.
With the exception of totally-not-Lego Megatron (Legotron?) and Nezha himself, the designs are kinda "eh" though. Which is a shame, because traditionally Chinese aesthetics IMO lend themselves rather well to mecha in general, especially when they draw influence from ancient armour and the geometric patterns of traditional art. I dunno, seems like a bit of a missed opportunity.
