Good start
a few things to point out would be:
Muldlines, they really ruin a paintjob no mater how good it's painted.
also picking out details makes the mini "pop" and gives a nice look.
And go over the mini after you have painted it to see if you have gotten any paint where it should not be, preferably before you hit it with wash
Highligting is also a thing to look into.
The sharp yellow wire pulls the eyes from the overall mini and to the wire.
And last the base, paint the sand and dry brush it lighter.
all the nitpicking aside

That is a hell of alot better than my first a tempt. a Ultramarine that looked like a lump of blue paint
