I like it!
I hate to paint these guys, I have lots and lots of them, but only 2 are painted quickly.
I wish I could force myself to paint a company of them though (some day I will!)...
Ther're looking great Colosseum, and it doesn't matter actually what standard you put to yourself. If the end-result is satisfying, and you're proud of it yourself, then you can only conclude you did a great job on it! It's not up to others to decide for you how far into detail you should go.
But if you're open to improvement, we can always advise things if you would like so
And if so, I'd start to advise you to look out for Badab Black wash, to give the metal parts a wash so it gives it a bit of shaded and darker look in the deeper recesses.
Keep it up mate!
Oh, and about the paintpots, heh, yeah, I know that feeling. I once got a load of old pots from a friend of which I had to recover most. I does take patience (and cursing and broken skewers and dirty fingers) to recover them. Keep 'em wet though, cause once they were dry,they will dry out again much faster. If I'm not bothered with a pot which is getting dry, I just cover the top-layer of the paint with a little water, so only the top-surface is wet and completely under water. It will prevent it from further drying out... (but that's it actually, it won't make the recovering easier later on).
