Searched a bit more in here and I think I'm trying to do something like this http://www.scirra.com/tutorials/290/3d-sprites
But, my game needs to have a bit of comic style art.. so I need to check out if sketchup can do that.. else I'd just have to draw them on paper and again redo them on tablet.
If you have a better solution.. please share :)
@Joannesalfa: Did you mean using a 3d modelling software.
I don't have skills/time yet to use any 3d modeling software. Also, I'd think for the current game using a 3d software would be a overkill.[/QUOTE]
If you have time to learn 3d modelling using Blender and Sculptris http://www.pixologic.com/sculptris/
then generate a sprite with differentes realistic angles, if you can master 3d modelling
