i think this image is perfect. especially if you're going for a magnification effect on those robots on the left. if you aren't maybe making them a little bit smaller and further to the left appearing would fix up the issues you think exist - but i don't really see any as long as you give a creative explanation for their size through the glass
the only thing I find strange on the perspective aspect is that the second robot is too small (or too low) comprared to the first one and the camera's angle. But apart from that, this piece is beautiful !
Awesome concept art I was wondering, the huge robots / robotic suits beind the glass on the left look as they were immersed in water. This "feeling" is created by the "distorted" prespective that makes their image look flat against the glass surface. Is it the effect you wanted to acheive or is it caused by your being "totally not good for the perspective view."?
The details are great, and there's a really nice atmosphere on this one. But yeah, the perspective does need some work. to be honest, I always find perspective really hard to get right digitally, but on paper it's really alot easier
