Drawing sunflowers

Some drawing practice recently. I love sunflowers and I like to paint them. I did some more practice on using ink and later on decided that I'll color them despite drawing on sketch paper. I was very careful with the amount of water I used so that the paper wouldn't buckle.

I will admit that I struggle a bit with upturned leaves, drawing them folded and curling in or out. I guess here I got lucky, I was pretty much winging it.
