Very very nice. Now this is a piece, I would love to see hanging in my room. The colors and texture are amazing. There's an amazing amount of good flow of energy, as you worked your way around this piece. I like how you used a light "scraping" effect (like the patches of red on the bottom of the painting and at the top center) and gave it a sense of rawness. The amount of white that you used, in my opinion, calms the tone down, so it brings balance overall.
Also, I love the amount of depth you've added here; the layering is really cool. Almost like at given points, certain lines are mirror objects of each other. This is also achieved again with the color choice. But then again, not to contradict myself, but the light shadowing effect going on in the background also achieves this.
Lastly, What I like about the straight lines: The vertical lines seem to catch my eye a lot, which compliment the height and tension found on the right side of the painting. For exapmle, the blue structure found in the middle, right side (tension) help create a "tunnel" effect, let alone distance. Then the top, right side helps to build the illusion of height, esp. with the empty space found right underneath it. Like if it was a scene from a movie depicting a castle with the main gate raised. Furthermore the color associated with this, with what seems to be a wall because of the darkening effect along this "gate", also helps to further define height.
Thank you very much for your comment, it made me look again at this piece, which is more of a practice work... and notice elements that I've left out when I was making the final paintings. The roughness of it is somewhat due to the little amount of time that I spent on it, and yet it makes it just so much more interesting.
You really made me think, so I'm going back now to the piece I was working on and do weird stuff to it xD
