Interested in a critique

[Joe the Dragon]

This is the first time I've asked for a critique, so its almost experimental.
I drew this about two years ago, always liked it, but also always felt it could've been little better.
I hope I uploaded it right...

WELCOME!!!

Tu primer trabajo artístico es muy, muy bueno. La tonalidad que tú has elegido es muy sutil y agradable a la vista.
Y has aplicado muy bien el Sticker para la piel de los animales...
Me gusta mucho.-
