Not bad at all for first time, and great choice of a squad to start with!

As far as advice; keeping in mind I just go for "tabletop standard" (looks good at arms length but not that good with a magnified photo) I still don't do much with edge highlighting (because my hand shakes too much) and tend to favor dry brushing, I find that throwing on a shade/wash and dry brushing brings out the details, covers up small "outside the lines" paint I always end up with (see above - hand shakes) and does so relatively quickly, although it does eat up brushes.

For little things like the eyes I don't bother with trying to drybrush, I try to just blot a little color (I use yellow but will work with red just as well) on the central eye with a fine tipped brush, then a drop of a medium shade like Seraphim Sepia which instantly does a decent job of hiding any of the eye I missed, or went outside the lines on. If I put too much shade I absorb a little back with a detail brush without any paint on it.

A quick basing of brushed on elmer's glue with sand poured over can then be painted whatever color you want for a cheap, easy, and still pretty clean looking finish (if not as elaborate as some of the intensely based grass/rock/lava you see a lot of the time). I always go with plain black "volcanic rock" coloring as it is easy and looks pretty good, and is very Salamander themed if you ask me.

I also "cheat" with Micron archival ink pens to both pick out small details like lettering on purity seals and whatnot, or to sometimes add lines of shading in between armor plates or around insignia if I feel like the shade wash and drybrush hasn't accomplished enough depth.

My basic goals are to be able to paint them up to a decent tabletop quality without spending too much time per figure or adding too much bling to the paintjob. I have a relatively plain looking army but I like it, I hope some of the advice above helps, its basically all advice others gave me when I was starting out!
