1. I only put 3 spikes on the head. I know you can only see 2 spikes but there's another one on the back, but I'm not drawing another thing just to show you 1 spike. I just didn't think it was necessary to have all these spikes going down his back and tail. It's not that I didn't wanna draw it, it's because since he's more lizard in nature, I didn't think it was necessary to have all those spikes.
2. His under belly before was white. I changed it to a lighter greenish yellowy color since it goes better with his overall coloring and his eyes.
