After putting this through the tablet, Its much more clean, and looks very well done.

The Blue is what I am planning to add scenery. A lake (so the fish looks like it came from water and not from a parallel dimension), rocks and a tree. Though, I don't know how to draw accurate scenery, that's why its only a "sketch".

So, I changed a few things, I made the neck look fluffier, added a little bit of stomach fold, and put my left paw down. Also, I thinned out the ears.
