Wolf boy, pixel test

I'm taking a dip into the pixel art world, so I did some tests on what size I'd perhaps like to use most of the time. I made a random wolf boy, just winging it. The small one is 64X64 and the larger one is 128X128. I made the smaller one first but by the point of making the 128X128 one, I've felt like i already enjoy it more than the 64X64 one.
