Welcome to the forums!
Stellar tabletop jobs on both of them, but I think there are some parts like the cloak of Boromir that really stands out being great. Overall you seem to have a grasp on painting what I think you should try out now is boosting the contrast with layering on all surfaces.
You could try following a tutorial on this site or maybe a GW one. Dilute your paints with water and mix in more of the highlight or shading color little by little. Smooth the transitions out by washing over the surface with very diluted paints (maybe 1:10 paint/Water).
I\'m not sure we can fully appreciate the minis because of the pictures. Improving your photo will make it easier to place constructive comments. First of all, use a proper backdrop.
the camera seems to be descent so you should be able to get some better pictures. Try reading the articles on photography. Especially the photographing with just one lamp article. Secondly you could visit the \"photography\" forum and look at spacemunkies article on photoshop. (You don\'t need to use a gradient as a background though)
and if there is any language-barrier, just ask.
