What you referred to as 'slacking off' is one of the best deviations I have seen. I wish I could show you a picture of my pharmacology professor, it's like you painted her! They look the same, lovely and intelligent. Congratulations, a well deserved DD!
Ha! I found college extremely useful for my art as well. How else was I supposed to stay awake through chemistry classes? I haven't broken that habit yet...... Its a beautiful piece too! Love the mood tho the flowers on top keep pulling my eyes off what I think should be the focus of the composition. Still far better than anything I can pull off!
