Josh Groban

^_^ Lately I've been going through my music playlist and I've gotten reacquanited with my Groban songs Lovely lovely voice this man has! Anyway I decided to do this portrait of him (reference pic from [link]); this is most definitely dedicated to and for my wonderful, real-life friend - her 17th birthday is tomorrow!!!
I'm really starting to enjoy drawing portraits, and there's just something oh-so-very soothing about it....I'm still trying to get the hang of proportions (his forehead seems too low ) and accuracy as well as shading techniques, so any critiques and advice is most welcomed
I kinda got lazy towards the end and botched up his neck
