I always start an animation and end up having to stop because of some work that enters and consumes a lot of time and then ended up going to other projects and that animation doesn't coming out of blocking step. But I will post some here more for nostalgia, because some of it have 10 years old or even more.
Scared Ball
This one for example I was using the Softimage XSI to animate, one of the firsts animation I did when I start studying animation in Melies School. I remember to animate this one in 2009, but I only post on Vimeo in 2011.
Ballet Cliché
Just a cliche body mechanics exercise started in mid-2012, this one I already migrated from XSI to Maya.
Vivo - Mobile Company in Brazil
Okay, this one I finished and it's not just a study, it was made for a mobile company in Brazil called "Vivo" in 2011 as a work for Digital 21 Studio. I will post here because it is also nostalgic for me. At that time I worked at Digital 21 for a few months and we did many, many animations of this company with this character who is the mascot. Very cool remember this..
