(angry hunter custom minifig by sir nadroj)
As far as custom minifigs go, this is one of the most angry minifigs i’ve seen, I’m not sure if the minifigs face is custom or if its a decal, but the weapon is a brickarms custom, the orange tabbed minifig tab, however, really helps define this as a Lego hunter, all its missing is a deer, or maybe that got away and thats why the minifig is angry.

There is a whole movement is minifig customization and in the Lego community about customizing weapons, these custom weapons are modifications of brickarms minifig weapons, however there are other minifig weapon modifications that use only standard Lego parts, and even more impressive there are modders who will make custom lifesize MOCs of weapons in Lego.
These minifig scale custom weapons however are really well customized and they look very well done, with only a handful of small errors.

This MOC is brilliant, its designed as part of a larger Lego MOC, interestingly the sandbags are made of round four stud plates, and the roof camouflague is really cool especially with the netting, as you can see there are loads of Minifig accessories, and the whole MOC is minifig scale, this would look really cool with some custom minifigs in a vignette.

This is a really nice fantasy custom minifig, with custom weapons, a minifig cloak, a custom helmet and a cool chain weapon, apparently this custom minifig was designed for Dungons and Dragons, a board game, not really related to Lego, the modifications to the weapons are really great and help give this custom minifig more character and in Dungons and Dragons this could be great for showing a characters powers, weapons and abilities.

This incredibally ornate and detailed, Lego castle MOC is fantastic it’s full of great detail and there is an amazing Spiral staircase, there are also portcullis with gates, jail cells, torture chambers, secret entrances and trap doors, its perfect scale for Minifigs, and would be great with a few custom minifigs thrown in.
