A little bit... I sanded the top of the head down where the most roughness is , because that was on the support/raft... that will sand down well though... I sanded a little bit along the ear sides where the artifacting occured. I know those little bits are starts of layers, even though i have it inside out... not sure how to get those out of there. Either way, i dont think its going to be a hard process to get this ready for paint. 2-3 coats of paint will hide most of it.
