Red Vintage Cake

First paid order I did for a friend’s 30th. She requested an all red vintage cake. I made Italian meringue buttercream and was so happy with how it turned out plus the color red that I was able to achieve 😍 However, tbh I wasn’t happy with the design I did or the quality of my piping for this one 😢 just felt like it wasn’t my best work 😕 Besides that, this was also my first 2 tier cake so I was happy that I was able to execute that! Top layer was 8 in and bottom layer was 10 in and both were 4 layers tall. I’m curious what some opinions would be regarding pricing for this?
