depending on which Brother your doing I would say you need to build out the mouth area a little more he looks a little short in the beak at the momentI also think you should experiment a little more with what you are using as a texture stampLance's texture looks like lots of tiny balls because they are raised giving texture to the surface of the sculpt ( i'm sure they weren't done with balls of clay individually ) while yours looks like the end of a tube which leaves the surface flat and just cut into which is all good but you loose the surface texture that will look great in different lighting and also cover up and inperfectionskeep up the good work and experiment more with the finish
