Welcome to the forum. These are my thoughts...
Both images are soft. You have a nice lens but neither shot, in my opinion, benefit from the f1.4 aperture as it will yield a very shallow depth of field, as chancey noted. Maybe you were shooting that wide open for the low-light???? You would do well to use a tripod (or monopod if you've got a steady hand) in these situations, increase the f-stop # (smaller aperture), and decrease the shutter speed. I don't now how the 40D handles noise at higher ISO so all I'll say regarding that is that an image with more noise in it is usually preferred over a blurry/out-of-focus one.
The softness/lack of sharpenss and the "busy-ness" of the first image doesn't make for a good image. I really see no point of interest in the scene, nothing to direct my eyes to a specific area. Had there been a deserted bicycle in sharp focus, or maybe a solitary person enjoying a cup of soup or something in sharp focus that could be a focal point for the viewer it may have worked.
The bottom photo lacks sharpness, it seems the highlights in the gold areas should shine more. Some of this could be camera shake. Being at 1/60sec you are close to the focal length of the lens...any camera movement could soften/blur the image...in a perfect world I'd want my shutter speed to be close to double my focal length, but sometimes we have to compromise. I like the slight angle of the photo...the tilt and expanse of area to the left of the statue draws my attention to the ornate gold area. Most people concentrate on the statues...I like that this image concentrates on the background.
Keep shooting. Maybe do some experiments using higher ISO settings in low-light situations and find out what noise-level you are comfortable with in those situations.
You might want to google "Bryan Peterson". He's got lots of good info and tutorials on the internet. One thing that he talks about are "story telling" images. Here is one such (short) Youtube video... https://youtu.be/KG9s-zR3jC8 He has other videos and tutorials regarding this (and lots of other things)...check'em out.
Also, for depth-of-field, you might want to visit this webpage... http://www.dofmaster.com/dofjs.html It is a DOF calculator...you plug your camera, lens, f-stop, and focus distance into the calculator and it gives you the depth of field that results. It is good for getting an idea in your mind of just how shallow (or deep) different lens settings can affect DOF.
Best wishes and have fun!
