Browbones tend to slope back while yours is the most prominent part, compared to cheekbones. The face also looks kinda flat instead of curving with the typical angle of a skull (like if you see a head from directly above, it's not flat on any plane). Jawbone also tends to slope back and upward because it basically "hinges" at the ear. Highly recommend using life as references (photos, life drawing; phone camera + mirror = lots of self made references)
