Hi, I've noticed your recent image uploads and I'd like to say that they're a pretty good start, but there is a few visible issues. Namely anti-aliasing with your and camera positioning
You can remedy the anti-aliasing problem by downloading a pre-configured dxsupport.cfg which can be found here Help:Model_Viewer. Replacing your current dxsupport.cfg with the downloaded pre-configured one will force HLMV to use the highest graphics possible.
For the camera positioning the main thing to note is not to make it too close to the class's face but instead show some of their torso as well. Another small little note is to make the images angled where the class does not directly faces the camera, though only a few of your images that almost had this issue. Heres an example of an image with good camera positioning
If you need any further help or explanation you can reply to this talk page or add me on my Steam page which is found in my user page. (Note: I may not respond very quickly as I'm dealing with a few complications in real life)
You're doing good so far, but you can do even better!
