That's a very nice, very neat paintjob so you've obviously got some skill with the brush, so I hope you don't take it the wrong way when I say I think you can do better. Add some shading and highlights to the cloth, some depth to the metal through inks and highlighting, and the mould lines on the helmet are pretty glaring and should have been sanded/filed off as well.
The base is also nice, but could have benefited from a bit more variety by including some dirt, some 'tussocks' and tall grass, etc.
I really don't want this to sound discouraging, because you've obviously got some talent and it's a nice, crisp paintjob as-is, I just think you've got potential for more
