Nice work so far
This pic shows the challenges of modelling/painting Japanese armour (at any scale)
However, some thoughts ref the lacing (odoshi).
As the vertical laces support the row of laminae beneath it, the upper row of lacing would be the same as the upper lace above it. There were many variations on lacing but during the Age of Warring States (Sengoku Jidai: c1467-1615) plain basic colours (often dark blues) and simplified armour, often with solid lames and widely spaced lacing were popular as they were more functional.
MiniArt don't give a date, but looking at it (and yes, there are many errors), it looks like a fairly early one, perhaps the most likely lacing method for the figure may be:
See refs below, mainly from Abselon's book on cuirasses (do) show lacings and colour variations:
There are many useful web links, eg:

Restorers sites also give invaluable information and show the mechanics of lacing etc:

Otherwise, the figs swords are wrongly mounted. For much of the earlier period the main sword (tashi) would be suspended from the waist and a dagger (tanto, later a longer uikushi) thrust through the waist belt (and spare bow string holder if using a bow).
(this also shows the long no-dashi sword, as used by kikushio on Seven Samurai and the bow string holder)
In the later period, the longer (katana- a little shorter than a tashi and better for fighting on foot) and the short sword (wakizashi- the two together known as a daisho) would be diagonally thrust though the sash (obi) with the blades uppermost. This was especially a fashion when wearing 'civvies' .
However, throughout the period there were many ways of mounting the swords and the 'old' and new styles (tashi/katana; tanto/wakizashi) could be mixed (suspended best if on horseback) as:
The shoulder guards (sode) don't look right either (the refs above give refs)
