Hi, your image work has improved greatly after me and Vasya told you a few things, but there's still a few things to improve that I'm here to tell you.
The first is cropping. Some of your images aren't properly cropped and empty space takes up the image more than it should, this makes images in the pages to appear smaller than they should.
If you use GIMP to do these pictures, you can crop the image by going to Image -> Crop to Selection. But after that, try pressing Image -> Autocrop Image. This will, namely, autocrop the image, not leaving any unnecessary empty spaces.
The second thing is transparency. By looking at your Globetrotter image, you're simply removing the background from HLMV to do these, right? Well, there's a proper way to do these, that will properly remove background from translucent/transparent stuff.
This is how it should look like: File:Item icon Globetrotter.png. See that the transparent areas weren't removed. This is because the process I used from above.
For consistency's sake, it's recommended to always use this technique regardless if there's a translucent or transparent item. Especially when it comes to Sniper, which his glasses are always translucent.
Finally, speaking of the Globetrotter image, the default style is for the "Snow" style, so the Infobox image should use the Snow style instead.
Other than that, you've improved a lot, so thank you for listening our feedback.
