Thanx for your comments....

For the whole day I'm assuming you mean 24 hours...
Okay, I made a little painting with Don guide to show the painting steps...

First step was glueing all the stuff together. Not the easiest part with all the fine details...time: 2 h.
Didn't make a pic here.
Next step. Base colour black and the first silver 45 min.

Next is the flesh tone. I use Foundry Flesch B. Time 10 min.

Next step light brown for nearly all the bows, Spearshaft B, Foundry. Time 25 min.

And some red for the english....

Vallejo flat red. Time 25 min.

Next are white and light blue (Sky Blue B by Foundry). Time 35 min.

Next steps are dark green and dark brown (Forest Green A and South American Flesh C). Time 30 min.

Next I fixed all the parts that I missed so far.
After that I got the Armypainter-Wash on: Strong Tone, Dark Tone mixed. Time 45 min.

And the last step, the highlighting. I just use the original colour over the washed base colour. So far: flesh, white, blue, silver and red. Time about 3 hours.

And you have to add the drying time.
I would say round about 9 hours so far....

Cheers,
Don
