Nice try on the gradation of the colours, looks pretty smooth. Base is a bit lacking in comparison to the rest of the work. I would expect to see a little bit more of shine to those gems.
There is a huge mold line on the arm that holds the sword, you can try to smooth it with a razor blade or filing it, that way you will get a better final result and it wont affect your paint work that much ;)
Hope to be of help ^^
