Tile Requests (Custom Bosses mostly)

I am using the DoR tileset, and I am no good at drawing tiles. Hopefully either some good artists would be willing to make me some tiles, or maybe they already exist somewhere. Any and all help is appreciated.

First I need to make my Level 1 Boss... a giant snake. The fight will take place almost in a Donkey-Kongish style arena. (Ledges and Ladders as opposed to the top-down view) The boss needs to be 2 tiles wide, be able to be three different heights (low, medium, high), and appear on either side of the arena. The idea is that he is under the ledges and pops up on either side at random heights and breathes fire.

If anyone can help that would be great... I might be able to release a demo soon.

Some other boss tiles I know I am going to need:
That Eye thing from Misery Mire (Lttp Lv6 Dark World Boss)
Big Octo (LA Lv4 Mini-Boss)
Koume + Kotake + Twinrova (Spirit Temple OoT)
Sprites for Din + Nayru
Aghanim (That wizard guy from LttP)
