it is so good to share things in this forum, a lot of expert and professional people give me opinions, which are very useful for me. I love to listen.
totally agree with you, as a concept designer, technique is not the most important thing. shayd_lady, You have a very good eye, you could see what i am strong with and weak on. hehehehe

, but i am not come from product design field, and have never be a product designer,
anyway, thanks for ur comments again
