But in this case I tried to make it slightly different by using a real perspective instead of isometric (or axonometric) view, which is most often used for such illusions, and higher field of view showing areas both below and above the horizon (so we see the lower part of the castle from above and the higher part from below). This was quite challenging, because the principle of the Penrose triangle doesn't really work around the horizon. You may notice that both in the lower and in the upper part of the picture there are numerous bridges between the towers, meeting and intersecting in some crazy ways, but there are not so many around the centre of the picture. That's just because the same principle wouldn't work there. But still I hope I managed to make it interesting.
Such a fantastical tower you've designed. I wounder how the people constructing and residing within this structure must feel about the optical illusions thrown all over the place. Just one flaw: Where the heck are the two other walls!?
I am amazed by how great this looks. The lines are perfectly straight, and give the piece the same feel as the illustrations in older books, (including, considering the Escher theme, books on geometry and optical illusions) and the line art is great, with you knowing how to use as few quick lines as possible to give the illusion of depth efficiently, without messing up the style or forms. I am sure that you must have been meticulous in your attention to detail, and therefore the viewer should will have to look long and hard to fully appreciate this. Considering that themost worthy comparisons to Escher are the result of the geometrically impossible figures, such as the storeys and buttresses, and the cube hanging from the hook up top, your patience, in order to ensure that the lines are perfectly straight and proportionate, is incredible. The slightest error would have ruined the effect, but I cannot really perceive anything wrong with this. You must understand geometry a lot, as you were able to draw the contradictory planes and contours without getting confused and disoriented. Just for the meticulousness alone, I have to rate this as one of the best artworks I’ve ever seen on this website.
It has just the right amount of detail to sell the illustration and right amount of complexity to fascinate with the impossible.
As critique, the lower stories (pillars) could have been just a little taller so that the little people could not 'reach out with their hands and touch the impossible'. I think part of the impossible constructions fun is the mental journey on the path, like the ant on the mobius strip, if you follow what I mean. (if they can touch the impossible, they don't need to make the journey.)
I agree with you, perhaps the problem is that I wanted to put too many parts and objects in a limited space, so they are often too close together – more space could certainly benefit them.
I really enjoyed devising both the impossible outline of the structure and various details, including the people (for a time I hesitated whether to include them, but I am glad that I did so).
The abstractness of the castle itself, and all the detail looks really cool, and seems to show you more the more you look at the picture!!
Great job It really feels like an Escher piece!!
