A very good deviation. But I think it could still be improved. Like I said before, this style is wild and sharp. The roses petals look great, but the rest needs to follow. Add more curve to your leaves and let them wisp around. Also, the thorns don't stand out very much so you'll have increase the size of the stem to allow for more of them. And remember, use negative space for emphasis of details when you can. Furthermore, it may just be me, but it really seems to make a piece when the edges and points are all crisp and sharp. Your endings are a little bit round... Anyway, I hope this helps more than hurts. I really am trying to give you useful pointers. So if you decide to use them tell me how it turns out.
Well, I looked through your art and the works like these in your gallery are the best in my opinion~ And the grafitti picture you did. Now, I'm not all that good of a critic on art like this, but I'd say it's very good!
