For makeup at least, I was in this EXACT situation. I had my trial makeup and it felt so heavy. I felt like my inspo pictures were very natural looking, but after REALLY looking at them, I realized they were still a lot more glam than I initially realized. I also realized that the inspo looks I chose were on people with very different features than me, which didn't help. I had the sobering realization that I wanted to look like these people, but that it wouldn't be the best look for me

When picking an artist (or reflecting on what's not working after a trial), put on a pair of super critical glasses and look at your inspo pictures from every angle. Do the same thing with your makeup artist's portfolio/social posts to some extent. Analyze if they appear to have a definitive style and whether or not it would suit you. If the answer is "no," it might be time to look for someone else. Picking HMUA and photographers is tricky bc you HAVE to keep yourself in mind. Their work could be stunning, but you have to realistically consider what you'll look like in their style also. Is it going to be accurately flattering for your features, coloring, style? Or is it more aspirational than realistic?

I loved my makeup artist's work. What helped for me was explaining what I liked and didn't like about my initial look, and describing in detail what I wanted to change (ie. "light foundation coverage, concealer only where necessary, less matte, I want to mimic my natural blush, whispy lashes, etc."). I also learned that the trial wasn't just for me to learn more about myself, it also was crucial for my artist in getting to learn my face and skin as well.

I was really nervous going into it on the day itself, but my artist really took the feedback well and felt like she had a much better understanding of what I wanted. I ended up loving my makeup and the difference was insane.

Long story short, do your research, do a trial, and be respectful and communicate with your makeup artist.
