Welcome to EPZ Sandra.
This is quite a lovely shot. The pose of the bird is really nice as it seems to be looking around the flower.
So the question first. You mention a bigger crop, to show the dew on the beak. I take it that you mean a closer crop, that is with the bird larger in the image?
Since the bird is quite small as it is, you risk quality if you want to crop closer, and you have no guarantees that the dew will look better, - but it will look bigger.
This has to do with the size of the cameras sensor, - essentially how many pixels you have to play with, the ISO (noise) and the sharpness of the image.
You are using P mode, - so you may not yet be familiar with the settings that give you more specific control. The settings the camera has chosen look reasonale, and the lens, - assume its an IS, stabilised lens, is a good quality lens.
If its the Canon 100-400L, it has quite a reputation for not being very sharp at 400mm btw, - its a lot better no longer than 350mm.
However, the camera is an APS-C sensor camera, which means that the effective focal length is the actual focal length of the lens, - 400mm here, multiplies by 1.6 which is called the crop factor. So the effective focal length you are using is 400 X 1.6 = 640mm.
The rule for minimum shutter speed when hand-holding a camera is that the min shutter speed is 1/(effective focal length), which is 1/640, or the next higher speed if 1/640 is not available.
This means, that even with IS, the shutter speed is marginal, and may be a little slow. Theres where the benefits of controlling what the camera does come into play. Using shutter priority, ot Tv on the Canon, you could have selected a higher speed, and let the camera do the rest, which would increase you chances of a great shot. Its still really good btw!.
Anyway, - I wouldnt crop closer. I will download this and see if I can make some improvement in a modification which I will upload shortly. To see any modifications, scroll up this page; click the modifications tab; click on a modified image to see it larger; and if you see an option for view large, click it.
The mod Ive uploaded is cropped to a 10 X 8 aspect ratio; this leaves more space on the right, the direction into which the bird is looking, - this can improve the composition. I was indecided about the upper fower, but I did eventually remove it.
Enjoy the site. Hope this answers the question and gives you some ideas.
