Wow! I think this is one of your best pieces! I really love Tay's face and the background in this! The pokemon look really cute and happy and it's nice to see some of them interacting with the background rather than standing in the middle of no where and looking at the 'camera' The colours look great and aren't too bright or too desaturated! Though my only complaints are the sizes of the pokemon look really off to me and her boobs are too far apart;; But other than that great job! Keep up with the great work! Oh! And I'm sorry if this seems a bit rude to ask but when are you going to announce the winners of the writing competition? It's been four months now TTvTT;;
Pretty decent, but her chest looks really weird... Like, her breasts are set too far apart, and the left one (our right) seems to be facing a bit sideways? Her one shoulder is a lot wider than the other, and the lighting seems to be a little weird in places; the light seems to be coming from the top-left, but the shadows on the characters (particularly Tropius) isn't always consistent with this. Take care to make sure shadows and highlights make sense, and not just stuck on willy-nilly!
Other things that could be improved: her lower leg is a touch too long, and it looks like her hairline is a tiny bit crooked in relation to her eye line. I feel like her collarbones could do to be a little further apart, too. And this isn't a mistake so much as I want to point our that her skirt is so short that her panties would be quite clearly visible when sitting like that (covering maybe only 2/3 of her butt); was that intentional? If not, you may want to consider lengthening it a tiny bit for future drawings.
Otherwise, great drawing, and if you take my advice into consideration I'm sure you'd get even better in the future!
