This is a fantastic job for a first mini! It could use more contrast (darker shadows, lighter highlights) in some places, but that's something I'm still working on after almost 3 years, so understable that that's the case on your first. I like the bracelet and the helmet particularly, and I'm really impressed with how nice a base you've got for a first mini, bases intimidated me when I first started. I really hope you'll keep up with it and look forward to seeing your future works!
Now this mini is very good, I give it 6.5. I think that You will be a great painter, 'cos this mini is much better than half people can do after years:P The colors are not "top notch" bit like Snow White.. But my are similar:P
Good job.
