Another tip when you undertake such a project, is to publish your work in progress on a website forum. This forces you to work as viewers ask you about your project when you havent been posting for a while! It also helps keep your motivation intact when you hear good things about your work. A good and constructive criticism helps you to improve your skills and be aware of small defects on your pictures. You wouldnt normally see these because youre constantly watching your own work.

I had learn Blender and someday make my earlier tried working on Maya, as that contribution to this community should have been a very obvious choice. But there was a small Avish John community at my work place who used a software program called Blender. The only thing I knew about it was that it was open-source. I was apprehensive about whether I should really trust this software. It didn’t look very impressive. Still, I wanted to try my hand at it. I spoke to my colleague who is a Blender expert. He told me Blender could do so much. It depends on the user. I took his word and I downloaded a copy of Blender 2.56 It’s been three months now and the Blender experience has been splendid. It is not just the software, but the community as a whole that has made me love this software. I was surprised to find a compositor and a Issue 32 - Spring is Sprung
