Alyson hannigan colour pencil

well i got a new scanner for my birthday.. so this is a better version of my drawing but still not right.. i need to read the manual lol..

First colour pencil portrait and first attempt at using colour pencil on white paper... man i take my hat off to all you portrait artists lol this was hard! i learnt a lot.. used lots of the wrong colours and ended up making mud in a few parts.. but being my first im trying not to be to hard on myself .. easier said than done lol... photo isn that great im thinking about buying a new scanner for future pictures this size.. or else not taking photos at night lol
my girlfriend is a big buffy fan so this is for her
