Makeup advice please!

Nu

Hey ladies! I've been out of the makeup game for about 6 years. For Mothers Day my sweet husband gave me a wad of cash and told me to go shopping for myself since we haven't been able to afford that for a while. I spent 150 dollars on some pretty nice makeup and as it turns out I don't really feel like I know what I'm doing. Mainly with false eyelashes and contour. I got powder contour and I feel like I have massive brown lines down my face no matter how hard I tried to blend it. And I don't know if you can tell in the picture I'm going to post but my fake eyelash edge on the inner corner is pretty visible, does that mean it's too long for my lash line? I just feel like it isn't close enough to my lash line but I have very thin eyelashes naturally so maybe I'm just not used to having eyelashes. Any other advice is definitely welcome and I promise my feelings won't get hurt so throw it all at me. Thanks everyone! 😊
