Nice paintings. Both paintings are very good. I like the first painting better though, because I like the theme, colours and the natural pose. It also looks sharp and detailed, yet not over done. Your second painting uses a lot of rich colours, which still looks good. I can only say that in comparison to your first painting, your second painting seems to have lost definition around your nose. And, your pupils are bit small, which doesn't look natural.
I guess it was quite awkward for you to take a picture of yourself whilst brushing your teeth?
Anyway, I can honestly say that you are a good artist. I can't paint or draw portraits, but, I do have good attention to detail.
Keep practising. You're doing great!
