Thank you for the feedback :). I didn't think about the idle animation that much. I saw that grey pixel just after I posted it and now it annoys me a little :P  

I look forward to create more stuff!

This is pretty great, especially for a first attempt. I think as far as feedback, I would say lengthen the idle pose just slightly so that the loop flows a bit nicer and there is one grey pixel that comes in and out in a distracting way on the left leg. I also think that the deep brown/red under the hood should be a little darker, but it still looks good regardless. Great job, I look forward to what you make next.
