solid work, especially the checkered plate on the chest is done very carefully. I can't say that i'm much better, but the way to go from here for you to improve would be to work some more with thinned down washes and inks to get the transitions smoother. but you won't need that unless you want specific exhibition models, what you got there is excelent for tabletop.
6p because it's better than average tt quality
+1p because you've got potential ;)
