Actually, since the new guy is differently colored from the first, it's good to see that you can work under a pallette that you haven't made yourself. Working under restrictions is good.
But yeah, you really should make your own pallette. Try to improve upon what bengoshia gave you, and you'll grow.
Also, bengo, I don't think he's using your edit, he's just basing the new guy on him.
It's not 100% good in every aspect, but hey, some chameleon:ing never hurt anybody, it's a skill in itself. Maybe he's using blue magic and now have learned the skills you attacked him with?
Well, anyhow, bboybeatle, it's looking good!
I'd suggest you play with pallette to see if it's improvable. Shading on hat is weird. What shapes are you trying to convey? Face on new guy is great.
Then go over the old guy as well, we want to see what you can do with it, now that you've showed what you really can do, with the new guy O:
