Nemesis +Martin04, Comission+

This is among the best works i've ever done.
And i dunno where it came. Let me explain.

It all began 1 week ago, in my Gaia miniShop.
This guy PMs me (Martin04, the client) and tells me he wants artwork for his avi. I accept his request, and then he tells me that i can remove or add any item, as long as i mantain the essence of the character (not the exact words, i deleted the msg just before start working into this). At that time, i was working in the first Comission (Forward's) and thinking how i was gonna do the second one, cuz' i had no idea.
Then, i finish the first one, and when i check the references i had for the comission of MrsrachaelSnape, i complain about the hands position. Waiting for a response, i tried to sketch the final one (Martin's), and then i found the most amazing nothingness in my mind. Nothing!!
Mrsrachael told me i can change the position of the comission. Then i forgot about the sketch (thinking it was an easy one) and i told myself: "Don't worry, it wasn't a mental block. You're tired, that's all"
Yeah, i lied to myself.
Then, my pride started kicking right in my nose, yelling at me: "You can't let this happen! Draw again the Mrsrachael comission, i know you can do it the way she wanted!"
I re-draw the whole thing, finishing it with a smile in my face.
That was the last time i had mental peace in this month.

The very same day, i began sketching again for Martin, and guess what happened.
NOTHING.
Nothing at all. I couldn't draw him. I was desperated. Never before in my entire life i was unable to draw. The closest thing was when i couldn't do something the way i wanted to, but being completely useless was something new to me. My Halloween Nightmare. My Nemesis.
My mind sinked. Even worse, the next day, when i tried to relax, the image of the sketch appeared in its fullest, but fled everytime i was determined to capture it, leaving me alone and utterly hopeless.

I was thinking about leaving the request. Even wrote a PM to the client, but when i was almost done with it, a blackout left the whole street inside the darkness.
Determined to get some relax, I leave my house, just to discover a light coming from a little shop, a mile away from me. When i got there, the owner of the shop was cleaning the old arcade (here in México we call them "maquinita") where i used to play King of Fighters when i was younger (believe me, the face of any guy when a girl kicks his ass in a videogame is priceless). I inserted a coin to start playing, just to remember the good old days, and when i was selecting my characters, a white strike of creativity hitted me so hard my head started to ache.
I ran directly to my house, looking for a pencil and a white sheet, just to remember the blackout. Then, when i turned around to recover my game, i discover this little kid, about 5 years old, smiling madly and hitting the buttons of the arcade so hard i forgot about my headache, while he screamed at the top of his little lungs: FREE GAME!! WHOOHOOOOO!!

And Happy Halloween!!
