Good job! Definitely time for some more, finer brushes though! Check out the Army Painter line, they have pretty good brushes for a good price. As you progress with a steady hand and more detail, I can't recommend this highly enough. You'll look silly, but it's super worth it.
I use one very similar. I also bought from Amazon. I really find it helpful because I can add a second lens and can flip the magnifier down.
I can’t believe I completed my first mod without proper hand setting tools

These are helpful. That, and size zero brushes.
