Can't really comment on it.U didn't post the image links properly.
Use a site like photobucket or similar (Upload them then generate a link here) so we can have a look.
Very nice!
Now I suggest to take this on a higher lvl.
Extend the MOD by adding those cool glasses to every poke.
Can imagine that even on Animated 6 gen sprites (Gonna take alot of time though).
1. After 4.
2. No and yes. U keep all your pokes but if u wanna use them u have to keep in mind that the max lvl is restricted depending how many badges u already have in the new region (Anything above that is grayed out).
3. Yes.
4. Yes u can always return when your there.
