Looks good! A shame you couldn't make it in time though:/
Line drawing looks good, but I would advise you to work more on the shadows because in this way the drawings seem flat
Then it would be a good idea to also think about inking.
If you look at the latest Miyuki (and 2020 drawings in general) I've done now, and drawings i've done before, you can see me shading more than I used to. I'm still trying to get my way around it, as I have difficulties with it but we'll see.
As for inking.. Don't think that's something for me. I used to in art class but yikesssss, it was quite a mess usually. I wanted to try with these color pencils which I forgot the name of.. but its just a hobby and things are expensive so who knows
