You absolutely nailed the boss' bionik eye and the highlights on the teef of his iron gob. I could do with a few more details picked out, like the dags on his knee or a few chips on the armour, but if that's not your cup of tea, fair enough.
The loota guns do the job admirably. A small detail that would improve the look of them (imho) would be to grab some red and pick out their eyes. Devil of a job to do I know, but it's worthwhile if only for those occasions when you're posting close-up photos.
Trakk looks mint.
Thanks for the message! You know, overall I was dissatisfied with the amount of blue on the warboss. In the future I would like to change up some bits of the armour, and little details like that could then be able to be picked out with that blue. With the meganobz I was working on, more plates were grey. As a result, small details like that were more easily picked out.
Eyes, lips, teeth - all things I would like to do better. I've seen some great ork models with the eyes done, and I would like to get to that level.
Here is a "full army" shot - a bit difficult to get a good picture of haha, I ended up using the panorama feature of my phone to take this. 121 Orks.
Some unfinished projects:
A looted wagon of sorts, I haven't played a game in over 7 years, so the weapon loadout might be a bit strange. I've primed it and given it a dark grey layer, but I'm hesitant to keep painting it. Once I build up a solid group of vehicles I'll invest in an airbrush, and learn how to use that.
Another old project - there is a chimera chassis under there. The most reasonable next steps would be to extend the front out, and emulate the FW Gunwagon look. As it stands the front end is too small to accomplish that goal.
I had the lofty goal of making a looted Crassus Armoured Assault Transport a few years ago, this is about as far as I got with it. The top section hosting the gun mounts is magnetized and removable, designed to remove and switch out the weapons on the front.
