Taking on the camo challenge very nice. Looking forward to it. If I may give you a few tips (keep in mind I'm no figure painting expert). But I think you should thin your paint more. It applies much easier that way and the result is much smoother. The Mustard yellow undercoat on your test figure has a very coarse texture. Also the brown camo flecks are in some cases very thick.
And as Pat already mentioned the pattern does not match what you show as example. Try to get an idea of the build up of the pattern. You started with mustard yellow. Then the second darker mustard yellow. On top of that the bands of Grey. Then the brown flecks with the lighter edges. Easiest is to built it up that way and the final darker centers of the flecks are done as last.
Easiest way to create the camo flecks is by using a really tiny brush and almost stipple the thinned paint on. placing small dots that you connect to create the irregular patterns. That way I did some years ago my rendition of Oak Leaf summer pattern
The real pattern

The 1:35 pattern
Looking forward to your results.
