Wow! That is beautiful colors AND design. It reminds me of an old mermaid show I used to watch 'cause that's how they would wear their makeup. but different colors. I would try that if my mom would let me. I LOVE THE entire piece. And The whole thing is just tied together. Like it looks like different colors of green. (which is probably just what it is) I love Everything about it really. I couldn't do that. I can only do solid colors. And I have one question. Did you do this in yourself or did you have a model or one of your friends. (Sorry if this doesn't make sense I'm just typing what i like about it)
I like how the colors blend together so well and they complement each other. The colors bring out the brown eyes and the glitter in the shadow brings in light and reflects onto the skin quite nicely. The mascara is just perfect for the eye as it doesn't hide the shadow, but you can see it, and the black eye liner is applied just so. The small wing of to the side is a nice touch as well, but it could be made darker, or maybe a navy blue to match the shadow. The dark brown of the eyebrow combined with the reflective coloring of the shadow gives the surrounding skin a very pale look, which I personally think gives it a touch more character. Overall, I believe you did a wonderful job.
I use photoshop to get my skin looking a little better and to adjust the lighting, but If I take my pics in really bright natural lighting, I don't need to use programs just photoscape to make the collages
