Hi, and welcome to Smeargle's Studio! :)
Your art is really nice and detailed. I have to say the Gyarados would be my favourite, all I would have to say about it is maybe a slightly different choice of background? As in a stormy sea or something similar, rather than just a picture of water.
Like you said, the Dragonite is a bit too blurred, but without blur i'm sure it looks great, it seems that way.
On Skarmory however, I can see an issue with your shading: specifically, light sources. For the head the light source is top right, but the tail has it from the top left, and on the body it's both @.@ My advice would be, when you start a pic, to actually imagine where the light is coming from and therefore where it would hit/not hit, and shade from there.
Overall great start to a thread, hope to see more from you in the future :) On that topic, can you draw me a cute Purugly
