I was pleasantly surprised that when I looked back on this today, it didn't seem as bad as I thought, so I'm going to share it.
Apologies for the frog not walking on the spot!
It walks a lot quicker than I expected from the previews in photoshop, whew. It could even do with being slower, perhaps.
I'm working on a second one. I'm really trying to be disciplined with the volume of the character and the consistency of the lines, to avoid that low-quality feel. I can't wait to show it when I finish the next one!
Edit: I realise why it was going so fast - I was meaning to render it out on twos, each frame showing twice. Well, I've rendered it now, but it's become interlaced! Still more to learn.
