May have to do my own makeup

Why can't I do the eyeshadow right??!!

44 year old skin

Excuse the eyebrows

My wedding is in 3 weeks. I had almost 5 mths to plan but when I first asking around about makeup artist, most was not available during the holiday weekend, July 6th. There is a 17 year old that I know who does make up for all of the girls for proms & dances & she does a fabulous job. That is literally all she does is buy make up & watch Youtube videos. I went for a trial with her & she seemed to have caked on the foundation. I think it had to do more with the powder. I am 44 & my skin is older than the young ladies she does make up on. I am afraid I will have to end up doing my own make up & I want my pictures to be great...and my hair which I am doing on my own. Short hair. Anyway, I definitely have to get my eyebrows waxed some because they have gotten out of control and I will tweeze where needed. If I don't do that now, my make up will not adhere to my face. Anyone doing there on make up? What products do you use? Especially foundation that has good coverage but is light & won't emphasize wrinkles. Lol. I am at work and we are slow & I played with makeup...I have never been good with it. I was a tomboy growing up & just never work much. Thanks for any feedback.
