Interestingly, I even thought that this is a real drawing at my first sight! You know what, I like this creaton as is. It leaves a lot of space for interpretation and inspiration - in my opinion, this is an act of art already.
For example, when I work on my audio projects, I tend to over do the editing, mixing, mastering process to the point when it looses its raw, pure beauty - I've learned that after spending hundreds of hours on perfecting things.
I believe that there is more beauty in imperfect creations, because we can more easility relate to them, since we are imperfect too.
It is a real drawing... just very small :D
I like work that has character- and the same can be said for my audio taste too. I think this is why i like to listen to records on my old record player, the crackles add to the character of the audio.
