Mm, I'm always a fan if PMD 'fics, and I'm certainly enjoying this so far. X3 Your writing style is nice and light, and quite enjoyable to read, and your spelling grammar is good from what I can see- although I'm afraid I'm not viewing this on the best of screens. My phone's a little rubbish. XD I quite like your characters, you have a fun selection, and the plot seems intriguing.
At times, it'd be nicer to see you branching out in your descriptive style, though- at the moment you mostly provide a static list of features, such as 'the mouse-like pokemon was the colour of long unwashed socks, with a pair of black stripes darkening the ends of it's bent tail etcet.' This gets kind of dull for a while, and in general is slightly jarring: you halt the story to provide a description. Switching this style with a more subtle one, such as slipping the description into the story a little more, or using personification of inanimate forces to describe a setting, can bring a lil more variety. :3 Examples of each:
'The wolf lay curled at the base of the well, small shudders rippling across his muddied fur as he struggled to draw each breath, his stunted tail twisted at an awkward angle behind him. Crimson bloomed across his chest, stark against the silver before it bled into the wiry black that curved around his front legs, and he whimpered his pain, curling his trembling paws closer to himself...'
Not perfect, I know, but do you see?
Personification: 'A shrill breeze shrieked through the canyon, tearing at it's worn, red sides and scrambling at the smooth edges of the boulders that littered it's floor...'
Variety is the spice of life. :3 You have a decent amount of description, not too much, not too little, it'd just be nice to see a bit of a switch up. Experiment a lil. :3
On your characterization: I quite like your main character. X3 I'm interested in seeing how this all plays out. :3
I'm part of the review exchange, btw. :3
