[ wip ] Rainbow shark meets blue shark (Patreon)

I drew this a long time ago.
I found it in the folder from 2010 to 2013.

I've tried different illust with the same theme.

Blue shark and Rainbow shark.

Both named 'shark' but rainbow shark lives in fresh water and they are not even shark. 

Rainbow shark's size is 6inch(15cm) long.

Blue sharks are much bigger and longer, 

but if I draw rainbow shark too small, 

they can't be seen, so let's think of them as very bulky fish and still young sharks!

I changed the shark's mouth. A smiling face is always nice.

The freshwater tank looked too complicated, so I deleted it.

Instead, think of it as a dream of Rainbow shark :D

I changed the position of the shark's pupils and little fish to make sure they are eye contacting each other.

Thank you!
