3 Art pieces

These three art pieces were chosen from my art journal out of 12 art pieces. The reason that I chose these is not just because they are the better looking ones then the other ones but because I feel I can take these three art pieces to some other level change the color of it or experiment with it. I have put all three of these paintings into photoshop and have been experimenting with colors and shapes. The bottom pictures are the ones edited in photoshop. The other three are the original ones.
