So that looks like a good base painting, you just need to go over some of the smaller details again no biggie. Also that 000 is probably too small, I pretty much always just use a 1, and sometimes my 0. You got the reaper learn to paint kit, right? Why not start with the models in the kit, and follow along with the guide? That way you are getting your practicing done on models you've got no attachment towards, and it'll help you learn along the way. Oh, also also, you probably want to thin your paints more than you are already doing (if you are thinning at all). I'm by no means a master (or even all that good) and I'm still trying to get used to how thin my paints should be, but I usually put at least one drop of thinner into them. The paints are thin enough which means I have to do at LEAST two base layers, sometimes three (or more), but it makes the models look much better.
Speaking of thinning paints, is it recommended to thin metallic paints? I feel like every time I've tried to do that it just dilutes them too much and the shiny metallic part doesn't really come out. So those are the one kind of paint I've stopped thinning, but is that advisable?
SillyEskimo the potion on Baldric looks REALLY cool! I've got my Baldric primed, but have yet to paint him. Also your Karl (I think that's his name?) is pretty cool, as well. I don't have him primed yet, actually just got him with the Wulfsburg expansion on Friday. Here is one of the minis I painted today and I really like how he came out:
He's Apprentice Milo! At first I had his hat and gloves black, but then I decided "you know what, he's going to be the apprentice to my Necromancer!" and made the overly large hat and gloves purple. He stole the gloves, hat, book and parchments and is now fighting back against his evil master. As a model he also has the most successful eyes I've been able to do so far. Overall I'm pretty proud of him. The other model I'm painting today is a viking dude with an axe, and he's coming along alright but something about him isn't doing it for me. Not quite finished with him yet, waiting for the washes to dry, but I dunno...
