hi MM_Ghost_3D heres the screenshot of the back

can you post a shaded wire of your mesh?
heres some tips.
- be sure that all the vertices running along the middle is placed on the “0” (zero) x axis, and before applying the mirror, place your pivot on the zero axis as well- to do that-- select the object, then go to hiearchy panel, click “affect pivot only” then typed in “0” on the X value. after its done you can now click the mirror.
- be sure to remove any modifiers(meshsmooth) before applying a mirror.
- when following this tutorial, just follow the topology as close as possible, observe the position of those vertices and edges especially on those critical parts.
- dont give up. you will learn by your mistakes:)
