Sorry to hear you've been feeling low🙁 Hope things pick up.
This drawing is absolutely amazing though. Like Sammi-chan said, you captured the Teen Titans look perfectly.
Like Vlad said, draw what you feel, the result is rarely bad. I, for one, think this pic is awesome and yes, as always your Raven looks just like the real deal (Just like your Starfire, BB, Robin...etc😉)
As for the lowness, you know my SN should you need to talk🙂
