creature exchange [Iheadsetshiba]

Creature-Exchange for iHeadsetShiba who wanted a wyvern?  I couldn't do the armor/cloth deal, and I'm not sure this resembles the monsters you wanted it to, but I hope you're happy with it regardless.

Coastal wyvern because I find it hard pressed not to imagine wyverns clinging to sheer rock faces and then diving into the ocean, but I'm sure this one can work in a tropical area as well??
