Elder and outer

An artist is spending a year to draw every creature and monster mentioned in Lovecraft's works. A great source for future works. To my mental eye, the Deep One is a bit too froggy but the Colour Out of Space is ace. I've looked at his Dunwich Horror and its as accurate as the text suggests. I've read and re-read Lovecraft's description of it but just can't picture it. I'm not sure if that means Lovecraft succeeded - because the thing was unthinkable for a puny human brain - or failed because I couldn't form a mental image of it.
