@Toffeuy: It's a good avvie, but it lacks depth, as in it looks too flat. The background is the same intensity and colour as Kingdra, so it seems to pop out above Kingdra. My eye is drawn to the background more than Kingdra, so using either a less vibrant or a more monotonous background (never thought I'd suggest that...) might make it a little more focused on Kingdra. All in all, though, 8.5/10
@Exolios: In-depth will come later, kinda tired now. Both of 'em: 8.5/10
Just a note, no offence intended, that style is getting a tad overused...
