Some weeks ago I thought it would be good to make a list of all the stuff I thought were useful in my illustration career, not only for myself (I can easily lose track of these things) but also for others to easily find a lot of tips and information at one place.
You can find the list here: http://illubis.blogspot.nl/
If anyone has any other tips, like books or websites or anything, let me know please! I'm open to any other contribution or contributors. I hope this way we can help other (starting) illustrators as well.
P.S. I just started the list so not everything I ever read is already on it...
