Mr Chumley,
This looks great! I think your painting style looks perfectly fine on this model!
I'm in the process of painting up the Nuln handgunners and they are painting up fine. As for too much detail, pish posh - if people think they have too much or not it comes down to personal choice and what we like.
I will say this however, sometimes a less detailed mini will be much easier to make look good with simple ,clean painting whereas FW minis tend to favour washes very well!
Don't feel bad, you're a great painter!
