My works ! Please give me your VALUABLE advice!  

Waver,
These are absolutely gorgeous. I agree with woody that the" water" version should be solid white, however. You should be so proud.
Best,
Mark

ahh...Thanks !
How do you think about the one?

Beautiful!
But I still think the cups need some work functionally.

Perhaps the cups aren't really intended for drinking tea,
but rather to "start conversations"?

Yes
I will continue to modify !Thanks for your advice!

Hi,woodywood
The first "water" have three kinds of colour as a result it can change the colour by the change of the water temperature!I don't express clearly.I am so sorry.

Hi,william-holden-caulfield
I am not for "start conversation?！I just think these cups
are beautifuul in this form!

The cups are pretty but...
The cups are pretty but imagine trying to drink out of one. You would have to tilt that cup rather much AND lean your head back very far to drink from it. That makes it a poor design.
Either cut more of the sphere away or just make it more cylindrical and less spherical. If you want to actually drink from it, that is.

Well
The first tea set whole looks a bit complicated ,and the cup can design of concision simply.It is just my opinion.
I like the second

.
my rubbish renders...gone

Hi , *spanky*
This is a very valuable advice!Thanks!

I wonder if the "water" cup even CAN be drank (drunk? drinken?) from
It may be a physical impossibility, for those with noses. Have you tried to drink from this cup, Waver?
Perhaps that's the most succinct answer to the recent wave of queries about how to become a "successful designer": spend MORE time testing your designs for their intended purpose.
Or, spend LESS time admiring random forms & focusing on the status conferred to the "Successful Designer".

Why do you take away your picture !It is useful to me!

Well, william-holden-caulfield
You are right.I should pay more attenton to the function.You are a good teacher.And I DON'T use it so I can not do a corret judgment.I will care about your advice!Thanks!

Because it was bad design.
