How To Apply Makeup Tiny Green Eyes Want Pull off Lights

I am turning seventeen years old. I have quite bad acne. I've tried medications and cleansing my face every day, nothing seems to work. My foundation doesn't hide my acne throughout the day. I find I'm constantly applying it, which doesn't help my acne problem. I also have small green eyes. I like wearing make up like LIGHTS (Valerie Poxleitner) but I don't think I'm applying eyeliner and such properly. I'm trying to make my eyes appear larger, but I want to keep wearing my eye liner and such - because I know for small green eyes you're not supposed to. Please help/ comment with your suggestions. It'd be very helpful. Thanks so much. ~ Maddie.
