I highly recommend Krita as a drawing package. Essentially a free, open-source version of photoshop. It is what was used to create the π [MELN] logo.
There is no way to know for sure, but I still think you would have won Best Attack and Funniest because I personally loved your entry. The simple animation of your cat walking around and then distorting and destroying the background as it stares at the camera was hilarious.
If we do something like this again, I hope you continue to participate!

Hmm... ill have to look into krita as well... anything is better than paint.
That being said, i really love pixel studio on my tablet... the pc version isnt as good though.
