What are you most proud of, and what would you do differently next time?

I'm happy because I've used a lot of different settings that I hadn't used before, but I've done a lot of workarounds that I'm not sure what I've done right and what I've done wrong. Next time I'll organize myself better and do more research, but it's hard to know where I'm going wrong and how to get it right. I was a bit hasty and jumped into intermediate level projects. I'm looking for constructive criticism, but please be gentle.
