Here is an example of a pastel boa: http://www.reptilechannel.com/reptil...astel-boa.aspx, and here is an example of a blood boa: http://www.cuttingedgeherp.com/nss-f.../BloodMale.jpg. In my opinion, the OPs boa looks more like the first picture. Not only the color, but the pattern too. Also blood boas are dwarf boas, and the OPs boa looks pretty large for a dwarf. Just an observation.
