Many of you searching the internet for examples of academic drawings and paintings have probably already stumbled upon Kai Halmesvaara and his great blog full of eye candy, Inspirational Artworks. If you have not visited the site, you definitely should. Kai is a dedicated collector of digital images, and the archives are FILLED with pictures of two and three-dimensional realist artworks, and it would be easy to get absorbed for hours searching through all of the posts.
Currently, Kai is no longer updating the blog, however ; the Florence Academy of Art, of which Kai is a student, has asked him to maintain the school's blog, so for the time being at least, all new collections of photos will be posted to the FAOA blog. In the past couple of weeks, Kai has posted hundreds of académies to the school's blog, including several pages dedicated to the 19th century work created at the École des Beaux-Arts. Be sure to check it out (click on the Blog Archive for the month of June 2012 to find the recent academic artwork collections).
Kai shared with me that some of the images were culled from a French site, which can be viewed here.
