I'm no longer able to draw on the PC through the graphic tab but something gave me an alternative way to draw digitally. 

AutoDesk Express is an app both for iOS and Android, it's kind of like a mini Photoshop or Paint Tool Sai except that it only allows 3 layers for free... (unless you could pay money and get more extra layers and tools... tsk) 

I tried a couple of drawings, it was hard at first since you're using your fingers or pen but you'll get used to it later :)

The end results :)

Although, I am not certain that I can use this app for the web comic... =___=*
