Hi @mrFickle
Looks good, one of the rare paintjobs that looks better close up than further away!
But with some minor work I think it would look a lot better, here's a few things that I noticed:
1) The base rim should be black. Muted brown rims work in some cases, but I can't see beyond black with this paint scheme. I've never seen a brightly coloured base rim look good.
2) There should be definition between the blades of the chainsaw and the casing/blade. This could be acheived with a basic black wash. Personally I think that the red should stop on the "blade", not be on some sections of the teeth. The way that you've painted it looks a bit messy, rather than intentional.
3) The
OSL on the eyes is a good start (if it's intentional

), but it would look much better if you dotted the centre of the eye with a very light blue, or even white if you prefer. Most painters start off thinking that they will never have a steady enough hand to paint eyes, but it's not true, it's all about practice, practice, practice, and using the part of your painting hand or fingers to steady the hand against the painting handle to remove any shakiness. after you've done it a few times it becomes second nature.
When I started off in the hobby over 30 years ago I wish that somebody had told me this!
4) Not sure about the yellow indentations on the boltgun? I think that just shading the red would have looked better, which brings me to...
5) The red would look much better if it had more shading. Is this a contrast paint? Contrast excels when you add extra highlights and shades.
6) You missed the mold line on the head :(
7) Once you master drilling your gun barrels you will feel much satisfaction
8) I love the purple glow effect
I'm hoping that this comes across as constructive criticism, feel free to ignore
