Worked on this for animation class and liked this screenshot in particular. He's my little credits presenter in my final project of the term. Although sometimes hard, drawing movement is not a problem--it is finding the bloody sound effects to go with it that can take forever. In this case, I couldn't settle on any special call for my creature and I went through hours and hours of sound libraries to find the right yelp and footsteps. Don't even get me started on music and wind, I'll do that tomorrow after sleep and letting my legs unfold for a bit.
Toon Boom Studio 6.0 - It took me literally 24 hours only stopping twice for bathroom breaks and once for a ten minute meal. (I will never ever get my blood circulation back into my legs) (also, colouring sucks. I HATES IT)
