Creating ideas (sketch)

And another quick personal work just for practice.
And yep, actually I did another try to "30 minArt challenge" and I almost did it!^^
This time I noticed the time and I spend... *drumroll... about 380 minutes
-____-
But I am sure I just slept sometimes and didn't noticed it^^
Okay, not this time, but I will do another tries from time to time cuz this is really good practice)

So, what about Idea:
As I said - I wanted to draw it for 30 min and so I had no time for ideas (actually I just had no Ideas) so I disaded to draw how I creating ideas X)
But of course it is only one from many ways of creating it)
