I like it! overall a very good piece! my best suggestion for improvement would be a focus on the shading, such as under the thorax and abdomen of the spider. It looks like you didn't quite finish trimming it back. also your lines on the chin are a bit angular;I can see the spots where you dropped the line tool to make the next line. A little bit more time and fine tuning of the angels would help give it more of an organic look. Really enjoy the eyes. Solid piece, Keep it up!
