I watched your gallery and I saw that you use the colors very well, you have a really good technique. If you are not satisfied with the end result then you should experiment with other brands of colored pencils and other types of support (I use paper Fabriano Artistico mainly ).
Thanks. No I'm happy with the Polychromos and the end results. I experiment quite a bit with different brands. I'm always interested in how people put together their work, I thought your work has a nice finish. Paper I probably don't experiment with as much as I should.
