Zelda artttt! yeeeeey! :)
I like the background. xD
hrm, Zelda's forehead is too small or Link's is too large. :\
Also, the sparkles are in random places, so it doesn't really add that much... unless you're going for fairy
dust?
The light source on Link's face and sword strap thingy is different from the rest of the picture...
The coloring on the shield is a bit pixelated, might want to watch that. Maybe it was meant to show texture? But
it's not consistent with the smooth coloring elsewhere...
There are some weird perspective issues as well, mostly with the sword; the angle of the hilt and blade and triforce
don't align correctly.
And the hat is a bit flat.
Zelda in general looks quite fine, however, except it's strange that the top of her head is so flat when the rest of her hair has the strands drawn in.
otherwise, nice drawing. :)
Sorry if it feels like I destroyed the picture, because I like it actually.
