Gouache or Photo

Finally finished my painting. It's of my dress, took forever. I basically did stippling with the paint for the dress. The rest of the painting is like y usual work. I figured stippling would create the best effect and it's easier to blend paint colors naturally using it; especially when using gouache(doesn't blend well). I think my piece turned out really well and i happy with it.
