Forgive me if this is in the wrong section... So the other day, on deviantart, a writer puts a post in the job section asking for illustrators for some books he/she is doing. Sounds promising so I leave a message saying I'm interested, just one in about 400 other artists that left their calling card. Just got a note today from the author who says they liked my website and pointed out a specific style from one of my pieces but wanted a sample to see how I would approach their story. Now, I am not into doing 'samples' as this person has no nicely put it. My art takes a tremendous amount of time and effort and having to prove I can do a job just annoys me. Am I having a bad approach on this? Has anyone had a similar situation? Would you go ahead and so a sample if it were you?
