Ross deserves some tributes...
Nicely drawn logo and cool voice at the start.
My first gripe is with the buttons in the menu - you didn't change the graphics for the 'rollover' frame so it isn't as obvious as it could be what's a button and what's being selected.
iShirm's part was nicely drawn (although the animation was fairly minimalistic).
Doesn't seem very pleasant a 'tribute' though and as a tongue-in-cheek joke, it didn't actually make me laugh.
In your part, things could have generally been drawn better - specially the crumpled up paper.
I guess the end frame is meant to be charming in ist's simplicity/primitiveness? I think the two sides could have been clearer - are they meant to be cliffs?Mountains? and some of the lines you have could have maybe been omitted for a cleaner look.
I liked the jolly tune and colours though and the font reminds me of a holiday postcard.
It's a cool tribute and would certainly make me smile if it were dedicated to me.
I felt a bit underwhelmed by this though - might be the length or the lack of real humour or other substance (to my mind).
