What I wanted to do with this shot was to approach this vague idea of something born from sprites but focused on brushstrokes that I had in my head, and I do think this experiment got me closer to do it....but I do know it also produced all those problems you pointed out.
I accumulated a lot of impressions about dog breeds with caved in faces trough all the 3 months I worked on this, and I wanted to convey every single one of them in the shot. Therefore, from the beggining keeping a strict "model" wasnt really a concern at all...I guess the way characters transform in Ren & Stimpy allowed me to feel like I had a license to do that, but I do know that it's not as well executed in my shot as it is in R&S because in my shot there's not enough time to read all the drawings and I didnt make inbetweens where one shape sticks but gets deformed. Also the design doesnt have such clear use of basic shapes. That's one of the things I learnt with this, basic shapes really do read a lot more easily.
When the character is stationary good construction pays off, because you can turn it around very welll....and not doing that well enough might have caused me to miss emotion I wanted to convey. Not having a strict model doesnt necesarily mean vague construction.
Specifically I think the animator who did this short
http://vimeo.com/9115247 is more adequate at those areas and therefore woud have better served this shot in that aspect.
The choice to not use outlines made it a lot less readable, this should have more dark shades emphasizing the sillouethe and his face features to make it read more easily. I think I understand now that the reason so many animations have outlines everywhere is that aproach is less demanding on the pallete, if you rely only on shading to show your volume the contrasts have to flawleslly bring out the characters.
I knew I'd get this kind of comment here, and that's partly why I didnt post it here as I worked on it because I was trying something unconventional and the failing of things unconventional are specially easy to see from the outside so I was sure to get comments that would make me doubt myself and it might have made me hold back. Posting it afterwards like this I feel confident about what I tried and I know the limitations of what I did, so I still can elaborate and learn from the critiques I get. it's nice to be here =)
EDIT: Boy...every paragraph started with I...that's always been unsettling about the way I write C_c so much I, I, I
