Hi all.  I've got a few minis floating around that were painted when my skills were lesser.  Been humoring the idea of touching them up.  My finished minis are sealed with a coat of Krylon Matte spray.  Any tips for touching up minis?  Anything to look out for?

So I had this mini for some time, it was damaged, missing an arm and a hand. I repaired it using some bits and repainted it. Here's the WIP topic. I like how everything turned out, thanks for looking! 
Some before and after photos:

So a while ago I bought 10 of these prepainted wizkids merfolk minis off ebay for cheap. The paintjob on them is horrible but I like the sculpts quite a lot and my dnd group used them all the time during our underwater adventure campaign and was quite happy with th. One of them was missing an arm and I just put her in "to do" box and didn't use her in my games. After some time I chopped of her hand for another project and in the end I was left with an armless and handles mermaid.
 


 
Since my bits box has grown quite substantially during the last year I decided to pick something out for her in the arms and hands department and also repaint her. 
I will post updates on the process here and in the end make a new topic in the show off section. I'm open to comments, criticism and sugestions and I hope you like this proces!
Thank you for looking! 

Howdy,
 


 
Who's a good boy,
Kev!

So here's three more, just quick drybrushes but I think they are good enough for my dnd table. Hope you like them too! 
 
First one is an umberhulk:

The second one is also an umberhulk I guess (painted by my sister):

The last one is a gorgon, simplest paintjob but effective I'd say:
