Welcome to the world of minis :)
It's crappy but I can see you've made the effort to try some shading - the more you practice the better you'll get. Try painting a few more and see how much your technique improves. My first ever mini was about the same standard as yours - I wish I'd kept it.
Having fun is the most important part of painting! Keep this mini safe, and keep at it, and in a few months you'll be able to compare and see how far you've come.
