First (& as of yet, only) oil painting [Portrait]

This was (is) my first oil painting. It was the result of a 6-week course by The Colorado Academy's David Larrson. Essentially a 15 hour portrait sitting (roughly counting the breaks). As it was drying at home --- parts of it kept bothering me until I covered the eyes with a strip of paper... and "Wah-lah!". Presto Less Lamo!
As with oil, I guess I could go in and change things still --- but, being the first, I'd like to let it stand as it is... mistakes and all.
