Alexandru Serban - The Gate 2 is really good. I know it doesn't really fit the exhibit but I like it. I also like Krisztina Molnár - Old Town. The painting would be good but with the color its perfect. I guess my choices reveal my preference for a little more representational art.
Those are good picks and my favorites too. The good thing in art is that there's something for everyone, no matter what you like. As you see, there are all kinds of arts here and this is just a part of it.
