-reason-

People always said to me, 

'Don't work too hard for yourself!"

'How the hell you can be so patience to do that kind of thing?'

Well, 

I'm sure all of you knew,

I'm not good in 'verbal presentation'...
In other word 'very bad'
Nor experts in some kind of newest technology...so,

Let the drawings do the talking.

Manually.

Because in the end,

I'm happy to knew that I worked my ass hard

By selling my work 

On the papers and models

Rather than words.

p/s: Very bad verbally. No joke.
