They look nice, a good clean paint job you obviously have more than a modicum of talent.
Ok you asked for advice.
Paints it's a toss up realy which ever you can get your hands on easily is my advice GW are perfectly acceptable they have good coverage and an excellent range of colours a lot of top flight GD winners use them Jeremie B for one. For me though the Valejo range are slightly better and the bottle dispenser is definitely better than the flip top but hey the difference is very slight.
I'd push your highlites more for sure your contrast needs upping that is what makes your minis pop. Also faces and bases you realy want to push the highlites on the faces as they are the focal point of the mini.
Blending; this needs improving you need to graduate the changes in colours more smoothly so thin thin thin your paints and layer away. Each layer should be translucent so the lower layers showing through so it's smooth.
Spot colours add interest and help break up the overall image and draw attention to areas you want to emphasise ...but don't forget colour harmony which I won't get into here there's loads of articles out there on it.
Free hand and more involved bases help frame the mini and tell a story.
Copy the greats look here on C'MON gallery and blatantly copy what you like.
last and most importantly practice new techniques make sure you push yourself. Even if it doesn't work always aim to try something new.
Hope this helps
