More candy floss

Okay, so before writing this critique I have to say it's the first time I write a critique and my English is not perfect, but I'll do my best ! ^w^

First, what caught my eyes is the global composition (colors, forms, places of the items...).
Talking about the colors, I love how you used them ! Your piece is colorful, not too bright but not too dim at the same time.
I think the sky is really well done, and overall you used watercolors really well.
I really like all the details in this piece too, like the super cute cat, the hat (which is well detailed), the book, the pattern on the blanket...
The wavy hair gives a lot of movment to the composition, I can almost smell the scent of the flowers brought by the wind.
All this piece is showing a beautiful summer scene, for sure.

BUT, the only point that really bothers me is the girl's anatomy.
I can't exactly describe what is wrong, but her joints seems weird, or at the wrong place.
You can try, for example, to print out a copy of this artwork, and draw small circles where the girl's joints are supposed to be and for her head, and draw sticks for her members and the rest of her body. You'll see better where are your mistakes like that.
To me (but I may be wrong), her right knee is weird, like it's too long, and her left hip is too far from her body. Her right wrist seems too thin to me, too.
And for her head, maybe you should show a bit more of her neck, and try a bit of perspective, because her face looks a bit flat.

My piece of advice is to work more on the anatomy. You can take the pose by yourself, in the mirror or taking photos, or look at references on the internet or on books !

Anyway, this is really an artwork I enjoy (and the first I saw from you ! ^^).
I hope my small critique was useful to you !
Keep up the good stuff !
