Actually, I really like this one. It's freehanded, has decent shadows and highlights, and uses good colours. The problem is that you didn't really follow the UVM so the awesomeness of this texture got destroyed a bit. Also, you need to fix the width dimensions on this image to that of the original texture.
One of my other bigger concerns of mine is the glow around the lava cracks, it's a bit too big.
Overall it looks very good on the unwrap, but seeing as you didn't follow the UVM the wrap looks kinda bad.
Otherwise, great job. Just make some adjustments and this might get approved.
